A guy cums on a girls face, sprinkles pubes on her face, and then hammers in the pubes by using his cock while yelling "IT'S TOOL TIME"; giving the girl a beard just like Al Borland from the television show Home Improvement.
I totally gave that girl last night an "Al Borland's Hammer"! FUCK YEAH!
A vigorous style of masturbation, where the person or persons performing said act tightly grip the head of the penis in both hands and hammers up and down the shaft as if they were flattening a mighty slab or steel.
Joe: Yo bra, did Aaron really get medical choppered out of the Grand Canyon trip?
Greg: Yeah man, he broke his dick doing the Turkish hammer in his tent!!
