Gruntsquat 

See also O.H.U.B. and underbob
The act of squatting down....underbobbing...the resulting orgasm creates more of a grunting sound due to the position of the scrunched up body/torso. most times, body cramps result during the buildup due again, to position....resulting in one, nice loud grunting, painful yet strangely stimulating orgasm.
again, watch yourself on the overspray.

self explanatory. if you can't follow the directions, you shouldn't be jacking off. Go gruntsquat!

Gruntsplatter 

The simultaneous act of rubbing out a huge load, whilst exhaling deeply and letting out a loud groan of satisfaction

Jesus, Jennifer wound me up last night and wouldn’t let me have any so when I got back to my place I had to sort myself out, the gruntsplatter could be heard all through the neighbourhood!
