Courtesy Clench

When someone attempts and fails at performing a donkey punch, the reciever tightens their orifice in honor of the effort given by the donkey puncher.

Rob tried donkey punching me last night, but the dumbass hit my shoulder. I gave him a courtesy clench just to make the poor bastard feel better.

clinchy

When a young, beautiful female's long, blonde, gorgeous hair has been tousled atop of their head. For once in their lives looking rather unattractive at the moment because of the resemblance to a bird's nest.

This word can only be used in the context of a young Jordanian man referring to a young Latvian woman's messy hair. Offense should not be taken, as in the Jordanian culture, it is a term of endearment and love.

Jordanian: "Amanda, what is wrong with your hair? It is clinchy."
Latvian: "Screw you, hamza!"
Jordanian: "Oh, but you know I love you!!"
Latvian: "Aw, thank you then!"
