For as many times as you say it, you should just change your name to "I have a girlfriend."
We get it, man. You're getting laid. We're all super happy for you.
Other options include, but are not limited to, CMRA for "Creepy Mike Riley Avatar," ISoFG for "Inappropriate Shouting on Fridays Guy," or (and this is my favorite and real suggestion) IAAPNGBIGALE for "I'm a pretty nice guy bug I'm a little excitable."
