Glass Bottom Boat 

The act of recieving oral sex from a partner and ejaculating in that partners mouth. And before that partner can "spit" the fluids out you wrap saran wrap around their mouth keeping the fluids in place as they slosh around. Creating a glass bottom boat effect.

Mo was totally giving oral to this guy last night and before he could spit it out he gave him a glass bottom boat.
