5th Base

When a guy is having anal sex with a girl and he takes a large hoop earring, interests said earring in her butthole to make it gaping and then the male drops his balls into her butthole and removes the hoop earring for a tight fit of his balls in her butthole

Dude 1: Yo bro i just hit 5th base with this bitch

Base 2.0

Like second base, but much kinkier. Can involve hands way down pants, way up shirts, etc.

"Dude, me and Mattie went to Base 2.0 last night! It was hot!"
