Gal-Sneaker

Definition:

A man dedicated to the art of seduction is a gal-sneaker.

Exemplification of usage:

Her: Dude, you know you’re dating a man-whore…

Me: That’s not true, he’s a Gal-Sneaker. He makes sure you have a good time like you wouldn’t believe. A man-whore doesn’t even care if you come or not.
