I have no problem with you, you seem to be putting some effort into making them original, and I salute you for that.we're jus jokin' around yo'..
of course we're sayin' random stuff, its jus a little fun, stop bein so uptight and join in
However, I was under the impression that a "competition" would be along the lines of two guys facing off, taking turns insulting each others' mom. One guy comes up with something, you retaliate by coming up with your own insult and using it against him. Spewing nonsense that you picked up from other people just seems more lame than anything.
If musicians never came up with their own songs, and instead just copied the "original" few songs, wouldn't music get boring after a while?
If comedians all used the same jokes, wouldn't you stop watching stand-up after some time?
