>>29648432its either sm or sumo, why? because sumo only removes 2 letters and sm removes 4. You might as well say the full names because there's actually no reason at all to type the u and the o otherwise. While I don't really care, I can see how its stupid on both sides. If you're going to make an acronym, then do it properly. It's not 2/10, it's 1/5. Pokemon Ess Emm vocally has the same amount of syllables as sumo and is arguably just as flowing to say as SuMo, without the "hurrhurr its funny cause sumo hhurdurr".
What I personally hate is that people start trends with things that are supposed to be simplified, but don't simplify it to it's most simple form. It's a lot easier to type SM, don't ya think? Yes it is a .02 second difference to type SuMo rather than SM, so it's not that big of a deal - but it's still a retarded concept to just stop at SuMo. If you can't see that, then you're just as annoying as the people who bitch about you using it.
