Well, he's trying to get into an online game... does not go smoothly... he talks about thinking positive around 1:50... and then he thinks he get's into an online game after that... hence the manical laughing.. he plays a bit, talks trash a bit.. "you penis"... "i killed you"... "you son of a whore" and then right after that sentence, he get's killed... goe nuts, oops, there goes the keyboard, then asks himself where the escape button is.. haha
He then regains hope that he will play another online game...he actually get's one kill, makes him happy, for 10 seconds, then get's killed, and flips out again.
There seems to be some rage in this one...
