One that comes to mind that I've seen before are those psuedo-legendary/legendary/all dragon teams that usually looks something like this...
Dragonite
Salamence
Garchomp
Palkia
Dialga
Giratina
Now there is nothing wrong with having a team like this, but for some reason it just irks me because it's just a giant testosterone (hate to say it) noobish team. I can understand playing with a team like this for fun and all, but it's annoying when people gloat about how good they are and HOW AWHHEESOME DRAGON POKEMON ARE!!!!!111!!!!!1!!!!1. Along with the classic line of WHY WULD U PLAY WIT UU AND NU POKEMON U N0000000B?!?!!??!?!?!
Oh I don't know... I guess I just enjoy using my mind to think about strategies rather then plow through a team using one move.
People are so silly</333
