It’s the “drugs” part, dude.

Look, I smoke weed in an illegal state. I don’t invite my plugs to my house, and I sure as hell don’t agree to split rent with them.

Normal straight dude here. I’ve been hit on by a gay guy before. I explained the situation like an adult. All was good, no willies of any kind were had.
