When you're making love to a woman in the missionary position, but have to finish quickly, therefore you push her legs over her shoulders and keep them straight with your upper body, whilst continuing along with the sexual penetration in a frantic and rapid motion, much like a jackhammer hitting concrete.
"Bro, was at this chicky babe's house last night but had to meet up with the boys in 10 mins, so gave her the Calabrese Jackhammer and got out of there quick "
