Shlong Slap

After me and my girlfriend finished having sex she begged me to give her a shlong slap

Schlong Slap 

The act of using your underdeveloped third leg as a lethal weapon and proceeding to begin an extreme killing spree with the force of your massive cock being pounded against another's face.

Hey bro I cant wait to feel your Schlong Slap tonight, it feels so refreshing to have your meat against my forehead.

schlong-slap 

To be slapped with one's schlong.

1) I was fed up with her, so I decided to whip it out and give her a much needed schlong-slapping.
2) I really got schlong-slapped with work today at the office.
3) Whoever was working on this before me really deserves a Grade-A schlong-slap to the dome.
4) I decided to work out this afternoon and perfect my schlong-slap technique.
