look up any word, like the eiffel tower:
 
1.
verb.

sort of like a high-five, but you keep your hand in a fist when it taps your friend's fist. it can be used as a greeting or a goodbye like aloha.
shawna: hey, what it do!
fistclick is engaged, the convo continues...

colleen: well, i gots to get my hair did...i'm chunking the deuce.
fistclick again.
