Gilligan Gay 

When a man is not really gay but is extremely awkward around women, becoming nervous, tongue-tied etc. like the way Gilligan would react to Ginger on "Gilligan's Island"

Last night at the bar this really hot chick was hitting on my friend Steve, but he got all Gilligan Gay on her and totally blew it.

Daniel Gillies

An extremely hot New Zealand/Canadian actor who plays Elijah Mikaelson on the originals by CW. He is also know as the hottest vampire to walk the earth. He has an adorable accent and his character in every show he's in deserved better

who's that actor in the originals that deserves to be with Hayley? It's Daniel Gillies

The Dizzy Gillespie

The Dizzy Gillespie is when a man is giving oral sex to a woman who farts. The rank fart rolls upward into his mouth distending his cheeks like he's blowing into a trumpet. Thus making him look like Dizzy Gillespie.

My best friend fell out when I told her my husband was pissed at me because after date night I was gassy and drunk and gave him The Dizzy Gillespie during his late night dessert.

Jizzy Gillespie 

The act of ejaculating so voluminously into your partner's mouth that his/her cheeks inflate in the manner of a famous American jazz trumpeter.

"Holy fuck, Chris, take a full load I want you to Jizzy Gillespie."
