A Snail Trail is when a female leaves a sticky residue in their underwear or when they leave a slimy trail on a surface such as furniture, a bed, or on a chair. It will sometimes appear as a moist, damp, or a wet spot but will often resemble a trail that a snail will leave behind, usually requiring Lysol or
Clorox (both recommended) to clean up. It can appear as a fluorescent white, sticky, glue like substance that will harden if not cleaned up immediately, but will sometimes contain blood making Clorox absolutely necessary. If
the Snail Trail is brown, it can indicate the individual doesn't wipe their ass or they have a turtle head
peaking out. It may or may not have a smell, depending on the size and the color of the trail.
Example:
That girl I had over last night left an
epic snail trail all over my bed sheets and my
pillow case. What the fuck was she doing, riding my pillow? I had to use a whole can of Lysol to
clean that shit!
