This is a specific type of ratchet...one juicy j would likely say no to. This is a very large woman that also has ratchet tendencies (see ratchet). She tends to be the one dancing on tables/counters at parties when no one wants to see her there.
"That girl is a straight ratchet bro..."
"Do you see how big she is? She's a fatchet!!!"

"Oh shit there's a fatchet dancing on the table again and she's stripping...nobody wants to see that"
