etymology: terrorist + tits
The worst set of breasts you've ever seen. Breasts that haunt your nightmares. The image of them is carved into your brain. Thinking about kittens? BOOM. Terrortits. The sheer evil of these notorious knockers is why they're named after people who feed on others' fear. The malevolent mammaries of Satan's bride are out to give good boobs a bad name and turn those who like them into permanently scarred beings. Running away crying has shown to help cope with victims.
Seeing terrortits with your bare eyes may cause suicide. Discontinue sight if you manage not to kill yourself. Their prescence may shrivel testicles and kill small animals. If terrortits continue to exist, consult a hacksaw.
