Mainstream is what everybody knows. Boring stuff made by boring people to make boring money. It's made for the masses, and it's well known, because it's well advertised. If you're edgy you can also claim it's always worse than non-mainstream stuff.
Cult (also spelled "KVLT") is everything cool people like most. It's not mainstream, so your average Joe won't know it, the normie. If he does, then the thing is not kvlt enough, and you have to find an even "kvlter" thing. Example: KVLT black metal must be recorded on the worst microphone system possible (high quality audio is good for mainstream c*nts), and be only released on a limited number of cassettes (preferably less than 100). Cult films are films I better not talk about, because according to my definition, they'd stop being cult if I talked about them, and many people read about it here.
To be taken with a grain of salt.
