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."

Jizzy Gillespie 

When a man squirts his baby yogurt into the mouth while being blown like a trumpet.

Bro, I pulled a Jizzy Gillespie on her while she blew me and poured my baby yogurt all over her.
