I knew a girl we called Trout.
Because there are two things that smell like fish, and one of them is fish.
Actually, no, that's not it. She had this bf who she was really into, but every time she wasn't around, all he did was talk about how often he nailed her and that he didn't give a crap about her. It would have been sad except that she was a real ---Bad words, bad words, whatcha gonna do? Whatcha gonna do when saint censors you?---. He was making a joke one day about how he was having her from behind and it was making a slapping sound like a paddle ball... every time we saw her after that, we'd yell SLAP SLAP SLAP. We were laughing our asses off about that one day and I joked that it was like a trout you've dropped in the bottom of the boat, slapping around, smelling like a fish. After
that, no one called her by her name, they called her Trout.
I have a tendency to say things that stick around for a long time and take a life of their own (hello, mr speedbags).
I managed to convince him to fishhook her (same position as before, slip it in door #2, whens he turns around to complain, stick a finger in her mouth and pull back). When he said he did it, we thought he was lying, until she confirmed it for us later on for some reason.
