LoL... on my first day of High School my friend gave me the nick name "DaLulu". I'm guessing he didn't like saying Lulekani everytime he wanted to call me. Naturally I loved it.
Anyway a frame Trap is a move that leaves your character at advantage even when the move is blocked but it doesn't trigger a guard break animation (thats why its a "trap"). It means you won't get beaten out if you decide to attack immediately aftwards. Which is a contrast to how other characters are expected to play. Whether you play with or against a character with Frame Traps... its important to know what they are.
What are ya studying anyway ?
