When you bang a girl on their period, pull the tampon out by the string, whirl it around and throw it against the wall.

Run away!He has a dil-hammer!
by xXKillgearXx October 17, 2010

The act of a man standing in nothing but socks on carpet. He then shuffles his feet vigorously creating an static charge to which in unloads that charge through the head of his penis as swings it like a hammer onto the face of an unsuspecting person.
As my girlfriend was doing her make up I snuck up behind her and gave her the mighty thors hammer right to the jaw.

The girl performing the handjob proceeds to hold the penis only showing the head and proceeds to hammer the head with her other hand angrily, like the thwomp in Super Mario Bros. Thwomp hammers are common after the one receiving what appears to be a bad handjob criticizes her technique, leading to the painful act and loss of manhood.
guy 1: "I was getting a handjob from this girl and I tried to give her pointers. I don't know why, but she punched my dick so hard why did she do that!?"
guy 2: "Dude, she gave you the thwomp hammer!"
guy 2: "Dude, she gave you the thwomp hammer!"
