Marcorubio

An AR-15 rifle, named when a mass shooting victim said we should change the names of AR-15s to “Marco Rubio” because they are so easy to buy.

If you're going shopping could you pick me up some beef jerkey and a Marcorubio for tomorrow's hunting trip?

Marco

The moat homosexual name in the human language. Any Marco is definitely a homosexual and cannot deny the fact that they’re a homosexual. They crave men’s genitalia 24/7 and get a throbbing erection at the mere sight of any man.

I saw two guys make out on the train they were definitely Marcos
