this is when you take your hand, and in a wavy motion, stick it in there butt crack. it should look like a fish swimming into there buttcrack. it doesnt have to be directly inside, thats just gross. but over there underwear is fine.
-most guys absolutely hate this!
so have fun torturing them with this technique =]
i gave my friend a little fishy one time and he had a freakin heart attack. then got really angry with me and tried to do it back. it can be fun =]
this is just like the little fishy and the big fishy but worse. this is when you take your hand and make a fin-like-shape with your hand. Then really fast you ram your hand into the persons buttcrack. it should hurt them for a while.
i got a running jump and gave my friend a shark in the ass. hahahha! he waddled for like a week.... owned! >:D
