look up any word, like swag:
 
1.
Describing an individual who has latterly overindulged in wanking (usually upwards of five acts of masturbation in any one day) and is experiencing its concomitant and extended euphoria.

Often the wank-happy individual finds himself in such a situation when he, upon some windfall, comes into possession of a large quantity of high quality (usually European) pornography.
Ever since Alan got that box set of Danish Bean-Flicking Hole-Pluggers Dildofest Vols. I-IX, he's been so wank-happy.
