I got into an argument one time that i got really heated in and finally to end it i told this person i wouldn't piss in their mouth if there teeth were on fire....zoops!

I got told one time with this (possibly homophobic) one...

Me (to friend who is drinking pepsi): Pepsi is a poor man's coke.
Him: Butthole is a poor man's vagina.

It would've been better if it went like this

Me: Pepsi is a poor man's coke
Him: Vagina is a poor man's butthole.

i was arguing with a friend and another good friend was totally brown nosing and sticking up for her all the way through our arguement i eventually got sick of it and said "mate, shut the **** up. And while you're there, wipe the shyte off the end of your nose." not my proudest moment, but it comes to mind when its 1am and i cant think :)
