ROTFL!!!!
I know hey, I like BJJ as much as the next guy (that just doesn't sound right) but seriously, it's hella gay at times.
Q-Man, you think BJJ and wrestling is any good in fights? A lot of wrestlers seem to kick the ass of the regular Joe, even those that are good with their knuckles. It takes one sweep and you are pretty much fucked if you can't handle yourself on the ground.
Not sure. Never trained in it and it's not like I know a whole hell of a lot about street fighting or martial arts. Certainly seems like it has the potential to be effective in street fights, but like any other martial art, the level of effectiveness with depend to a large degree on the natural talent/instincts of the person using it and/or the level and type of training they receive, and what kind of threat they're up against.
The general rule of thumb in fighting outside of a ring is to strike first and strike hard, and not give a fuck how bad you hurt the other person. 90% of fights I've seen or participated in, the person who struck first won. This is why the meanest fucks normally win fights, not that they're more experienced at fighting or stronger or faster-- they just don't give a fuck. I've learned over the years that if you sense a physical altercation is imminent, the best thing to do is walk away (but if you got a weapon, keep your hand on it). You don't strike first, you stand a good chance of going down. You do strike first, you stand a good chance of catching an assault and battery charge or worse.
Take it from someone who's been arrested four times, stabbed twice, had his ribs cracked, his jaw shattered, guns pulled on him twice, tear gassed, clubbed, and tasered. Avoiding physical confrontation is best, and when you're not acting like a childish, reckless, self-destructive asshole, it's actually much easier to avoid fights than you ever imagined before!

But if you did want to train in a martial art for self-defense, ideally I think you'd want a combo of Muay Thai (which teaches you how to take and give fist and leg strikes standing up) and BJJ or Sambo (for grappling, joint locks, throws and groundwork), with some training in Krav Maga or Combat Hapkido. If you have a limited amount of time to train, I'd pick Krav or Combat Hapkido for pure self-defense purposes. Those are pretty much designed to handle real life self-defense situations with a minimal amount of training or even athletic ability. But the most important thing is to commit to the training-- which is exactly why I don't do it. I know I'm not gonna commit to the regular training required to make it worthwhile.
If you want one for fun and to stay in shape-- go for Muay Thai or some other kind of kickboxing. Fun, great workout, and has practical application.
