Meme wise? Garlic bread, frogs, and sitting in chairs the wrong way.

I thought garlic bread is for the asexuals and we have lemon bars.

But yeah, I feel like most bi culture is memes: sitting in chairs as mentioned, cuffed jeans, finger guns, the bisexual bob and many many more. But as it is with memes, they also change depending on the specific community. But I feel like we are pretty good with memes :D

But on a more serious note: Bisexuality has a long history. I think it's really interesting and I really enjoy diving in. Also being happy about every good representation, but that's queer culture in general I imagine.
