A frullet is just like a mullet, but it is backwards. This is shit because a mullet should be distinctly longer at the back than at the front. This hairstyle actually looks gay because if someone is going to grow a mullet, they should do it properly - business at the front, party at the back. No one should have a frullet. If you see someone that has a frullet, tell them to cut it off.
Note: A frullet should not be confused with a metro hairstyle (which are still okay but not as good as a proper mullet).
Friend: Look at that person's hair, it's so weird.
You: They have a frullet.
(You walk off)
Friend: Where are you going?
You: To tell that idiot to cut off their frullet.
