7. Trappers
There is very little worse than the kind of GTA Online douche-bag who will merrily camp outside stores, watching for any other players heading inside to rob the place, and then driving their car up to the doors to block the exit. Escape is impossible, and you're left helpless watching the trapper enjoying their moment, as you contemplate the only possible way out, suicide. Eventually, death comes to us all, and blowing yourself up is the only way to get out of the situation, especially if the trapper has chosen a particularly heavy vehicle, or is sitting in it, pressing the handbrake to make sure you can't push the doors open a fraction at a time. It's fairly despicable behaviour, and sadly it will happen until Rockstar does something about the door physics, or makes it impossible to drive that close to entrances. Even worse, they clearly enjoy the trolling...
Tips To Avoid Just make sure you're playing with people you trust, though clearly the video shows friends turning on each other for a bit of a laugh. If you find yourself trapped by a camper randomly targeting stick-em-up artists, you're pretty much screwed. If you see any suspicious, large vehicles loitering around stores, it's best not to enter.
