What is Prepeat?
1.
When someone reads your mind so that they can say what you are going to say right before you say it, thus making you look retarded.
my fiend said "i think its gonna rain"
and i followed right after repeating "i think its gonna rain"
so he says "yeah i know, i just said that"
so i replied "well thats your bad, quit prepeating me"
