give yourself 10 points
absolute credit to yourself
absolute legend
you ace'd it
don't ever do that again
you're ahead of the curve
you have a lot to answer for
you have the audacity to say that
you're a badass
you're being beastly
no beef with you
won't begrudge you an open-top bus ride
behaving like a creep
you're the best
my best friend and worst enemy
I'm your biggest cheerleader
'on your bike
bles yu
take a bow
you're box office
no-one likes a bragger
you are going to need a brand new pen to sign all the contracts waiting for you
calm yourself
you're such a card
charlatan
cheeky monkey
cherry picker
clever
clever clogs
congrats
congratulations
cool your boots
don't count your chickens
crafty so-and-so
credit
you deserve a medal
you deserve your moment in the spotlight
you drive me spare
you've earned it
encore
et tu Brute
to your eternal credit
you have been everything I thought you would be and more
you've excelled yourself
you'll go far
you're fast kid
I fear we have not heard the last of you
you've had your fill
you put the frighteners on
full marks
you're full of it
full respect
you're the future, kid
gifted it to you
you go girl
good 4 U
good call
you're a good egg
good for you
you're doing a good job
good move
good on you, mate
goody two shoes
all hail
you've got to hand it to you
hands off
hats off to you
you're doing my head in
I hear what you're saying
I hear you
your heart is certainly in the right place
go to hell
I won't hold it against you
hold it right there
hold your horses
imposter
impressive
not jealous at all
the job's yours, see you on Monday
you're just a Johnny-come-lately
go jump in a lake
you jumped the gun
killjoy
I don't know how you sleep at night
know-it-all
you know nothing, you know everything
you have lady luck on your side
you've got to be having a laugh
could take a leaf out of your book
how do you live with yourself?
someone I always looked up to
get lost
your luck's in
lucky beggar
lucky devil
lucky you
you're made
maestro
you've got the magic touch
your mastery of the darker arts
maximum respect
you seem to be measuring up the curtains
a mere whippersnapper
you're taking the mick
a mickey-take
you're in the money
you really should get out more
move along please
you nailed it
you're on my naughty list
nice one
I have nothing but admiration
obnoxious
come off it
like you're off the charts
you're off the Christmas card and present list
get off your high horse
you're off your trolley
that opens a can of worms
that opens Pandora's box
you make us look ordinary
get over yourself
keep your pants on
party pooper
pipe down
well played
you've played a blinder
you're one of those players I hate to love
you're playing with fire 
in your pomp
that's your prerogative
you're a pro
you did us proud
come on, pull the other one
pull the other one
I'll raise a glass to you
a real inspiration
respect
you've got the right idea
don't rock the boat
you rotter
that's ruffled some feathers
we salute you
see you in court
don't be selfish
you serpents of doom
you have no shame
shout it from the roof
show your workings
sing your praises
smart-aleck
smarty
I smell a rat
you snake
speak for yourself
can't speak too highly of you
don't spoil it for others
steady on, old bean
don't steal my dreams
do you want to step outside?
you're on a sticky wicket
you will stop at nothing
stop being a mean
stop playing games
stop thief
I like your style
surely you jest
I'm not surprised by anything you do anymore
what a talent
teacher's pet
you're a teddy-bear inside
throw a cartwheel
you're throwing shade
you've thrown down the gauntlet
tip our hats
you toe rag
you're top of the pops
at the top of your game
you're a one-trick pony
what a trouper
unthank you
keep up the good work
we shall not look upon your like again
upstart
you are so vain
very, very well deserved
do it your way
I like the way you move
you won the war, now you must win the peace
the world at your feet
worth your weight in gold
give you a yard, you take a mile
a yellow card for you
here's to you
youdunnit
your're on fire
