OneStarHero

A OneStarHero is the term for a sex act performed where the male shits inside the females mouth and she throws it up on his penis. After that, the male inserts his inside the females ass and quickly removes it in order for the female to shit all over his penis. Lastly he inserts his shit covered penis inside the females vagina and ejaculates inside her. It is referred to as a OneStarHero because only a crazed fan would let his/her one star or hero perform such an act on them.

I met Justin Bieber last night and after he took me back to his hotel room we did the OneStarHero.

oneupsetmanship

A specific variant of oneupmanship whereby two people compete over who upset whom the most. This process can spiral out of control when successive descriptions of why one party is upset causes the other party ever greater upset, thus passing the upset back and forth until upsetmageddon is achieved.

Jack and Jill started an argument which rapidly turned into oneupsetmanship
