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!"

While a male is taking a piss, the penis is clamped down upon preventing further discharge resulting in an internal backup of fluids (aka a water hammer) that causes extreme pain.
I was taking a shower with my girlfriend and had to pee, so I pissed on her feet and she turned around and grabbed my junk causing a pee hammer.
