The action of "wedging" (i. e. pulling) a garment or a piece of [[underwear]] so that a portion of its fabric is caught between the [[ass|butt]]ocks. This is typically considered an act of [[humiliation]] when done on others, but considered a sexually provocative act when it's performed by oneself.

Note that garments that naturally lie between the buttocks—such as [[thong|thongs]], [[fundoshi]], and [[one-piece thong|one-piece thongs]]—should not usually have this tag since the wedging is implied. 

For garmets wedged between the [[labia]], see [[frontal wedgie]].
