Refers to da humorous "I really like you" gesture of not merely slapping da other person's hand when ya smilingly offer said pal a high-five, but instead interlacing yer fingers with his and really "hand-wrestling him good" for a few seconds. A great way of showing a cute lady how much you enjoy/value/desire her companionship while you have hold of her hand, anyway; hopefully she will allow you to maintain your joyful clasp of said warm/soft extremity for an extended period afterwards, and possibly even accompany you on a hand-in-hand stroll around town afterwards if her current schedule permits.
A clasp-retaining high-five is an awesome way to initially "break the ice" with a new gal and get her head-swimmingly starry-eyed for you.. play your cards right and you may have her lying back on your bed stark-naked within an hour or two.
A form of high five that requires no physical contact. The two (or more) participants simply look at each other and say "Nice!" after one of them initiates the high five. The way this high five is started is that someone yells out "Hypothetical high five!" after which the participants count three Mississippis before saying "Nice." Friends who see each other often and use this form of high five frequently often develop facial cues instead of counting Mississippis before saying "Nice!" People who have trouble making eye contact with others have a hard time performing this high five and it is often impossible for them to perfect the timing.
"Hypothetical High Five!"
*1....2....3*
"Nice!"
"Nice!"
-A person takes both of their arms and raises them above his/her head and slaps both of their hands together as if giving someone a high-five.
-The idea is that someone like a home-schooler wants to give someone a high-five when they get a math problem right, but there is no one around so they have to give themselves the high-five.
Isaac, that was such a dumb joke! You should give yourself a home-school high-five!
The act of one going up to a girl and grabbing her boob and when she goes to slap you, you block it with your hand appearing as if she gave you a high five.
