shellback

A US Navy tradition that occurs when a ship crosses the equator. Any sailor or Marine who's first time passing the equator is subjected to a hazing ritual called "Shellbacking."

When I sailed with the 15th MEU out of Camp Pendleton I got Shellbacked.

penelope in a half shell

A person who is not afraid to show their inhibitions, while maintaining their corky demeanor.

Shellings

If something is shellings, it's absolutely amazing. This is most used in UK Garage/ DnB subcultures. Many variations of this word is used to mean different things. Shellerz/ shellington / shelby are all different variations meaning the same thing. If a DJ is "shelling down" at a rave, it means they're shutting it down with their lyrical skill.

"DJ Q's new album is shellings!"
