Girthgasm 

When a woman or gay man has an orgasm primarily due to the girth or the thickness of the penis they're being fucked with filling up their pussy or booty walls and making them feel so full, leading some women to squirt over and over again.

Nicole: Oh my God, it's so good, wow, I feel so full, right there, right there

Shane Diesel: Yeah cum for daddy slut, cum on this fat cock, have a girthgasm and go home and tell your husband, Myers, all about it

GirthusMaximus 

The ancient Italian God of Girth. He stretches vaginas to the maximum and fills them to the brim, and lets that sperm swim. He always looks good, smells good, and makes a woman cum more times than she ever knew possible.

1. Yeah my Gf was being a total bitchy cunt and trying to impose her bitch culture on me, so I just went GirthusMaximus on that pussy and made her cum 15 times and filled her up. Sent that mega bitch packing.

2. GirthusMaximus is a beyond god of pussy status, have you heard his bitch count numbers?

Gishgasm 

A gishgasm is an orgasm that is resultant from a "rascal-like" act. This is typically an orgasm of unrivaled quality. The term is used primarily at a few small private universities but it recently has been heard as far south as kentuckey according to sources.

Person 1: Hey you wanna break into that frat house and steal their roofies?

Person 2: Yes of course I do, that will ensure they never have sex until a new shipment comes in.

Person 1 and 2 proceed to steal roffies and escape.

Person 1: Ahhhhhh! Gishgasm! (Passes out)
Person 2: Your such a rascal
