An adjective used to describe a person's jealousy towards something. Pronounced like Gel-in. Sometimes used in a phrase: Jealin' like Magellon. The term has no relation to the famous explorer other than the fact, that they rhyme.typically a person would say," I'm Jealin'!", right after the other person in the convorsation said something really cool. The person saying it does not neccesarliy actually have to be jealous of what the person said.
Say the phrase "I'm jealin'" after a person tells you something really cool. For example, a person says "I'm going to the Bahamas this weekend." You would say, "I'm jealin'!"
