Bridge? Like, the card game? ELLY PLAYS OLD PEOPLE GAMES PASS IT ON
Probably a euphemism for smoking a bowl...maybe Mona is her dealer and they don't wanna leave any traces in text messages.
I suppose that makes more sense. But with all the talk of threesomes in the last comic's alt text my first thought was actually Elly wanted some casual sex. Whoops!
It's a euphemism for pot smoking. I learned it from a friend of mine! She played so much bridge she was kinda perma-bridged.
