Oh nooooo, not that one! Yep, that one. One of the most overused and annoying words in internet existence at the moment. This word in its most common context was basically cooked up by people with an awful sense of humor who have an inability to make funny statements. They then chastise people who are by accusing them of "trolling." Or something to that effect. Now I'm aware that there are certain types of trolling that fall out of this distinction but it's just become too broad and vague of a word to really be confined to any one meaning, and that is why today I will provide you with an alternate definition to enhance your vocabulary.
35. Trolling
Having sex with a homeless person underneath a bridge.
Man I can't believe I blacked-out and went trolling last night.
