Bisoning

When a male bison finds a female bison interesting he will stand directly in front of her and not move except to stay directly in her line of sight, as when a female bison wants to mate, they will go for the first male they see.

So bisoning is the fuckboy standing in front of you, horning in on your conversations and remaining there despite any and all attempts to move away or disinclude him. Basically the "I'm here, take pity on me, fuck me, I'm here, take pity on me, fuck me"

I tried to get away from Ryan so I could talk to this hot bartender, but he was a total fuckboy kept bisoning me all night instead...
