I almost forgot, my absolute favorite one is Afterbirth of a Lesbian Fingerfuck. Brother BlueBalls likes that one and I got to use that at work earlier today. I save it for only the best occasions.
Also I like saying fuckstain, cockfag, and dumbass.
Ahh, you stole mine! I notice I say it a lot when getting pissed off at anything competitive. Sometimes I'll top it off with "Fucking cockass mother fucker piece of shit." After typing that out it almost sounds like tourette's syndrome
