look up any word, like boo:
The act of having sexual experiences/intercourse in a porta potty (porta-john, porta-loo, portable toilet, public toilet, etc.). This is usually the result of extreme horniness and having no other place to hook up. This type of sex is gross, smelly, and humid because of the feces in the tank and the lack of ventilation. (verb) (noun)
Example #1:
Boy: Yeah my girlfriend and I were uber horny last night and had nowhere to go to have sex so we just went into the porta potty and porka-pottied.

Example #2:
Girl: I never thought this would happen but my boyfriend and I pulled of a porka-potty.
