A girl who dyes her hair so
red that while having sex the
sweat from her forehead blends in with her hair dye, causing the sweat to become
red and resemble period blood.
Bard: Last night was crazy. My bed looks like someone was murdered on it.
Derek: Seriously?! What happened, bro?!
Bard: I was having sex with my girlfriend. Right before she dyed her hair
red. Need I say more?
Derek: Goddamn Ruby Red Period Heads.
