when a girl wears her shorts so damn short they look like underwear.
Karen has her shunderwear on again today
Underwear that should have been thrown out but remain in your drawer because they never fail to save your ass.
I haven't done laundry for over a month, so today I was forced to bust out the shunderwear.
Underwear that has shart poop on it.
I found my sisters Shunderwear in the bathroom.
