It's just a dumb nickname. "RG3" sounds cool, "R3" does not.
Plus it's a nickname literally based off a nickname! (mindblown.gif) I mean it's based off "Rowdy" which is a nickname of itself so it doesn't make any sense.
At least RG3 is based off the dude's actual name.
Uh...can someone translate this to English please? Thanks.
Yeah, nickname based of of a nickname is kinda off-putting. Nonetheless, I've come up with some alternative (for both 3 Rs and 2 Rs):
3Ro (and 2Ro)
RoRo
and my personal favorite ...R-Trigger (as an alternative to the R3 PSB nickname)
