1)A term to describe the kind of women's underpants that are considered "uncool" if you're under the age of 60, or something. In this aspect they are similar to
tightie whities for boys.
Granny pants are usually high cut, with a highly elastic waistband that will come up to at least your belly button. They may also come in floral patterns, pink patterns, or other "old lady" looking styles- just like any other type of underwear, actually, anything's possible stylewise.
People who wear granny underwear usually wear it because
A) their mom bought it for them
B) they don't like thongs or bikini cuts
C) they're playing some kind of sport (oh, c'mon, you don't seriously think that all female athletes wear thongs, do you? Most "sporty" girls underpants are NOT thongs or really low cut.)
D) they just like them and don't care what others think.
Also called
grannie panties, granny underwear, etc.
