By definition, "faggotsaurus" is a derogatory term used to imply that a person is homosexual and therefore by extension an extinct reptile.
G: My brother is such a faggotsaurus!
A: I'm fairly certain your brother isn't an extinct reptile.
G: YOU DIDN'T DENY THAT HE'S HOMOSEXUAL.
L: Don't touch me, you damn faggotsaurus!
A: Do I have to wash your mouth out with soap again?
