I read all the catch prases of this thread trying to remember my own ones x]] I think there's two kinds of catch phrases: the ones for nice people and the ones for plain stupid jerks.
For nice people!
"Pffffffffff, relax. Look, the day is beautiful" - this one can work even if it's raining or whatever.. then it gets funny xBB *bad joke*
"[insert here any jokes/bad jokes that come to mind]"
"Can you lend me a pen? PLEASE? PLEASE! Pretty please *--*"
"..., you know, ...., and, you know ... You know, right?" - lots of "you knows"
"Like..., I mean, like... no, like... I mean..." - lots of "likes" and "I means"
" I love you. Thanks for the pen/whatever I borrow from you. Thanks A LOT. Really! God will reward you someday."
For plain stupid jerks
"Get a life. Dumbass."
"You mean that I AM STUPID? Look at the size of your ears, you Dumbo!" *walks away while the person tries to see the size of the ears.*
"You say that she is ugly? Com'on, you burn my eyes. OUCH! OUUUCHH, GET OUT OF HEREE! QUICK!"
Boring person: - Then while I was feeding my shrimp, he said..
Me with scared face: ZOMG, a cockroach!
Boring person: WHERE?!
Me: *run away*
hihihihaihaiah.
you know, i'm a pretty funny person x]]]
