>>1062783Basically this. A lolcow is someone like 'cado, where they act like a fool on the internet and are only popular because people laugh AT them, not with them. Some are jesters, who do it as a persona and don't act like that normally, just online. Some are too autistic to know they are being mocked, which is most lolcows, think chris chan.
Namefags are people on the sharty that put something in the name field for attention. Go on /pol/ if you want to see a million of them.
Boogeymen are believed threats who don't actually exist. On the 'ki an example is given, like if someone mocks a shitty attempt at a raid because the target isn't worth raiding, and OP thinks the 'cord of the person they are raiding found out and is trying to derail it. But simply nobaldi cares.
