look up any word, like tinder bombing:
 
1.
When you get a combination of shower water and cum on one or both of your feet after masturbating in the shower.
I got a cum foot last night when I was showering and I had to wash it off; it was gnarly, man.

2.
The result when one masterbates while bathing and someone steps in the leavings.
Seem's you have a case of cum foot Harry.
