Master Splinter was the rat who taught the Teenage Mutant Ninja Turtles, but that aint too important. I’m talkin' to the snitchin' ass rattin' ass niggas, and also calling them broke. When you’re broke, you can’t buy good clothes, so their jeans got holes in them, and all that comes out is one dime. Also, “drop a dime” is slang for snitch on someone to the feds.
