When a person has such bad luck that it influences everything you do. This luckalways comes in at the worst times and will always try to ruin your life. It can be with anything that happens to you. For example when you try to submit a due test or assignment and the system breaks down and it's marked as a zero. Another example is when a female come up to and you think she might ask you out or has a crush on you, but in reality she just wanted to bully you.
:Damn I got mad "Tybo Luck".

Hunter: He's soooooo hot! I almostsaw him shirtless!
Jacob: your such a tyboo .
