un high five 

works exactly like a high five but backwards(hands start together and move apart, making absolutly no noise). most appropriately used when someone says something omega lame shortly after giving them a high five
also to be used after giving a terribly limp high five

*hands clap in high fiving effort*
alex: that was complete crap we need to un high five and do it again.
connor: agreed

*alyssa and lucky high five*
lucky: that girl is hot!!
alyssa (crying): the only way i can feel better is if you un high five me
