slag 

(Verb) To reduce to an object (usually some type of technology or structure) to unrecognizable debris through the use of excessive firepower.

Verb: To swing your penis with the same motion and force that one would swing a baseball bat into a girl's face. At the same time, one must ejaculate whilst the penis strikes the girl's face, leaving a thick glaze of sperm on her cheek.
