Yet another colloquialism for being a male homosexual.

Derived from the phrase; "Men are from Mars, Women are from Venus". The reasoning for the term is if both planets were only populated with either sex they would then have to be gay.

That dude Ross is sooo marsy!

Are there any Marsies in this battalion?
