Tunder Yank 

When a girl stands behind you and pulls your dick between your legs and jacks you off.

Dave couldn't wait to tell Trevor and Taylor about the tunder yank he got last night.

Pretty much any sexual encounter. Synonymous with gettin some ass. Intercourse is known as "the tenderest of the yankee"
