Is that a euphemism, "a hamster"? Saying "a hamster" when you actually mean something else?

Me: This fic summary is "MCR goes on hiatus and Gerard finally gets his hamsters."
Mike: Is that a euphemism? Getting one's hamsters? It should be.
Me: It could mean losing your virginity, or joining the Mafia. Or, like... man, that really gets my hamster.
Mike: For when something isn't quite irritating enough to get your goat.
