RAB is a Roblox player, FNF player, and a YouTuber with 20 subscribers and uploads usually months or weeks. He calls himself an idiot since he IS an idiot, and a literal grinder in a Roblox tower defense game, Tower Defense Simulator.

Here's an additional note: fox, be actually honest lmao

A way to express: surprise, rage, love, happiness, sadness, being horny and not giving a fuck. It's more than a word, it's a lifestyle. Rabs is everything and anything.
You need to say it while feeling the emotions running through your veins. Use "Rabs" and you'll feel free.
"RAAAAAABSSSSS! You motherfucker!!!!!!"
"Rabs... I'm gonna cry..."
"Rabs...Anyways"
"Uhhhh it's so good...RaAaAbSsssS"
