Frat boys are college guys who are apart of a fraternity.

Bears are gay men that are fat and/or hairy. (Wikipedia’s words, not mine)

Raves are a type of party with light shows, glow sticks, etc, to produce a certain aesthetic.

Burning Man is a specific week-long party that happens out in the desert. Many camps are erected and it becomes a caravan city, essentially.

The comic is saying that the character who keeps get bad vibes from the bears formerly went to Goth parties and likely had bad experiences from frat boys at those parties.

In this case, though, because burning Man costs a ticket fee and alot of other things to go to, and because all the bears are gonna flirt with every guy and anyone who is even slightly homophobic is gonna get uncomfortable and leave, there are only bears around in the place they’re at.

the comic is a kind of diary so its about whatever beens going on in her life. She tries to keep track of amusing stuff. Think of it about things you might tell as a story to your friends while hanging out. Some can come off as straight out jokes but some are like: Ok ok. so im at this rave and man this total frat boy comes in and is looking at me and waving and im like. whoa. I want to get away from this guy. So just as im looking to get as far away as I can. Get this. He starts macking on this other dude. Not just any dude but he practically looks like he could be on field and stream. Anway Im telling my buddy about how my douchedar is way off and hes all like. Oh no worries there. Our bears strung out on molly make eye contact with anyone coming in to where the douches just skaddadle.
