Fap-Dap

Accidentally (or intentionally) high-fiving, fist-bumping or shaking the hand of an acquaintance or stranger, following a self-love session.

Dude...Clay was locked in his room for at least a half hour and then high-fived me. Something's not right.

Sir, I believe he just gave you Fap-Dap.
