When the bottom of a character's butt is partially exposed while wearing clothing that covers up most of their butt. Analogous with under boob, and opposite to butt cleavage

Underbutt is most often exposed by characters wearing minishorts (or hotpants more broadly), short skirts, or dresses.

Tagging Notes

• The character's buttocks should be at the very least 25% covered.
• The bottom of the butt should be visible without clothing being visibly pulled up or raised
• This tag should not be used if bottom of the butt would only be visible from a low angle upskirt view

Not to be confused with...

This section will list possible reasons for confusion, followed by the correct tag or tags:

• A character's butt being viewed from below, as if you're "under" it
• Use low-angle view or worm's-eye view instead

• The underside of the buttocks being visible through the thighs
• Use butt from the front instead

• A character that is under the butt of another
• Depending on the exact interaction use...
• facesitting
• sitting on another
• butt crush
• butt smother

• The underside of the butt being visible because of a low angle view aimed up their skirt or because the character is bent over in a way that allows the viewer to see up their skirt
• Use upskirt instead

• butt cleavage (the reverse of this tag)
• under boob
