A party where people stuff their faces with meat and talk about how they’re gonna be huge someday.

At the gainbang, my uncle ate six burgers and still said he was gonna bench 300.

The gainbang was so loud, my neighbor called the cops because he heard someone say 'glute bridge' too many times.

I tried to sneak out of the gainbang, but my friend grabbed a whole pizza and chased me down the street.
