An act displaying affection. Almost exactly like a kiss, except in the fact that "clacking" your teeth against another person's teeth is a nice experience, if no damage is done.
When we first klished, I knew that we were great for each other.

Kisses are fleeting, but a klish is forever.

the act of roaming the streets deliberately cruising for men with acute espresso-induced diarrhoea then watching the spectacle for the purposes of sexual arousal and facebook status updates. Popular amongst softball fraternities.
"did a hot klish in the middle of the street this morning in the broad daylight. That will wake you up quicker than a double shot of espresso"
