slough foot
The aroma your foot gives off after you pleasure your partner with your big toe. It can be performed vaginally, or right up the anus, whichever is preferred. It may resemble the aroma of a swamp or stagnant pond, especially when you put your shoes back on without washing your feet.
"Did you smell Travis when he walked by? I think him and his girlfriend are into kinky toe stuff, it smells like he has got a case of the slough foot today"
