look up any word, like dirty sanchez:
1. A male who touches other males' genitalia.

2. A great alternate insult for douchebag, cocksucker, or fag that won't get you in trouble at work, school, or otherwise in public.
1. There sure are a bunch of peter petters at this gay pride parade.

2. Dude, that peter petter in that BMW just cut me off!!
