Fluttering poos 

Intermittent flatulence with loose stools that make an apparent flutter noise as they exit the rectum.

My youngest son Tommy had a case of the fluttering poos after we introduced eggs into his diet.

fluttering 

From a root form of "flattery" but combined with the context of "flirting" used to describe someone gay being overly friendly with someone straight, but of the opposite sex.

I wanted to talk to that cute girl but that gay guy was to busy fluttering with her, hating on my game.
