Grumpenis 

General irritability, or GRUMPINESS, from a lack of sexual release or satisfaction. Can also be the cause of anger, short tempers and volatile behavior. Long bouts with Grumpenis may cause depression in some men.

It is recommended that Grumpenis be relieved with the use of a slumpbuster, twice daily, for a length of 10 days, if possible.

I haven't gotten laid in a month and my grumpenis is really starting to effect my overall mood.
