Typed slang is performative
I get that slang is a unique part of language and slides easily into a person's spoken vocabulary. However, when someone types in slang - I mean heavily - it takes extra effort and thought. You are fighting auto correct. So it's performative. It's an effort on an individual's part to look edgy and cool, to be part of The Something. But I think it fails miserably, and just makes the individual look stupid and desperate.
This is a post copied from another sub that illustrates this point:
These rappers is chopped cheese in the big 26 niggas is rats, snakes weirdos niggas got rapping bout the wat dey man did nd niggas be getting Peggy hilled in dey keister they talk bout us broke niggas all da time they making me proud to be a broke nigga broke niggas and streamers it's our year lol
I rest my case.
