Extremely matted hair that results from wild sex.
I went through an entire bottle of conditioner getting out the sex dreads that Gustav gave me.

The way your dreadlocks look right after having sex and the way they refuse to go back to normal for hours afterwards forcing you to wear a hat for the rest of the day. Depending on how bad you let sex dreads get, they can last for days, the reason being that dreadlocks severely resist change in their shape.
Corrina: you need to get rid of your sex dreads before the funeral.
