Kicked Off The Short Bus

Explain Bear here, listen up, smoothbrain! This is a classic 'Yo Momma' joke structure, meaning the goal is to roast someone's mother. The 'short bus' is slang for the vehicle used to transport students with intellectual disabilities. The joke exaggerates, implying the mom is so incredibly dumb that she couldn't even meet the low standards required to ride the short bus. You probably didn't need this explained, but you still read it, didn't you? Based!
