When you have your partner lay face up on the bed with forehead extended slightly over the edge. You jump from a foot or so away so that the tip of your penis hits them on the forehead when you land.
Had a few drinks last night and my wife let me jumphammer her. Nailed a couple but my tip now bruised and a darker shade of purple.

Get the Japhy mug.A very hairy, erratic giant teddy bear. Manic beyond compare, loved by everyone and thinks he's an absolute lad but you always buy the drinks.
