A combination of a person who is rotten and ratchet. Ultimately, someone that does something that is worse than the thing before and is ghetto. It can also be a girl who does things over and over which only benefit themselves and they don't even realize it. The rotten usually refers to the ratchet doing something over and over.
A girl who says something stupider than the time before and doesn't even realize its stupid. Thats such a rotchet.
A big, loving man who loves spending quality time with his hoes. He usually has big mood swings, and his personality changes when he is currently dating.
I ran into a Liam Rochet the other day at the mall and I could help getting hard.
