A strong feeling of the lulz, or lolz when one is feeling depressed. in other words, one is having a shitty day, one listens to some music makes him have a trolol-ocaust day. The music makes him think in ways he would not think normally, a euphoric feeling.
"So, Harry, after I smoked some weed the other day, it was weird, but there was like a... trolol-ocaust in my head!"
