Verb. For one to swing one's scrodum back and forth until a sound is heard. The sound can either be high pitched like a slap, or it can be deep like your ball sack is jelly. While swinging your fellow peers encourage you to trust forward harder, propelling the sack to make an intense clacking noise. The person who makes the louder noise with their ball bag is the champion of NYM&FR.
I thought it could never be done, it was terrible, yesterday I clacked so hard my sac started to bleed profusely. I screamed but luckily my friends were there to massage the pain away.

The action of getting ran into on a ski slope. Usually a result of a gaper taking slow, unpredictable turns that take up the entire mountain.
Dude that gaper made a turn out of nowhere and I clacked him!
Sorry I'm late, I almost clacked this gaper back there.
