Bizarre viral video shows woman using undies as a hair tie

Video of a woman taking her underwear off in the middle of a dancefloor to use it as a hair tie has gone viral.

Social media users are divided between those who think the woman is a problem-solving genius and those who think the "life hack" is just plain gross.

Footage shows the woman bending over and pulling down her underwear, which she then ties in her knot to keep her hair up.
