id have to say...
When Im fighting with someone else and i get them to low hp and i have low hp and some nub shoots a kamehameha at us and kills either me, him, or both (aka leachers)
pre-punchers...
kids who create servers and every 5 minutes they shut them back down...
terrible kids who say they own me cause they get randoms and i can block them
when i trans and noobs ki blob me (even though its legal)
when I am about to fire a beam and i get blobbed and my own beam kills me
when i have low hp and someone kills me they ALWAYS SAY "haha pwnt"
****ing krillen users who always sit in the corners and spam scatter shot...
The most annoying though is when im fighting someone and some stupid kid is spamming us so i cant see any of my opponents attacks cause im blinded...
(oh yah, i also hate solar flare)
EDIT---
This seems to be the popular thing... being frieza and throwing someone then finger blasting them... GOD THATS GHEY
