When your mouth is so dry (usually from partaking in the devil's lettuce, etc.) that your top lip sticks to the top of your teeth/gums giving the mouth a rodent appearance.

Typically used as in tickling ones mouth but also can be used in slang as in tickling a women's private region.

Used when referring to someone who is forever talking shit I.e. Referring to their need to use some toilet tissue to remove the bullshit which is forming around the edges of their mouth.
"I was partying with that hot blonde again last night."
"you talk such bullshit you need to wipe your lip."
