The sexual intercourse necessary to get you out of a funk. This act is best executed with someone you will never have to see again, and possibly while you are under the influence of alcohol.
The need for a "funk fuck" can be identified by constantly complaining about things you cannot change, or can change, yet choose to complain about instead of making an effort to change--usually job, weight, finances, etc.
(Speaking of a friend) I'm so sick of listening to her complain. What she needs is a solid funk fuck.
An especiallycreative sex session, often involving moves or positions not typically used during sex or perhaps an unconventional location.
We did it half dressed in an art gallery bathroom. The whole time we talked about mid 1800's French culture or poodles. Needless to say, it was a real funky fuck.
