Sigh...
OK, I've been in the hospital with a cat scratch/bite back in 2001 (my cat sitting in my lap tried to bite me and I moved my leg, causing him to fall mouth open, straight down into my arm.) They had to use the ?second level of penicillin? because the first try didn't work and I was starting to get streaks in my arm.
To Your Point: This song's been around for decades (I graduated in 1976 but only found out the ?intended? meaning maybe 2 decades ago. Yep, I'm one of the hip COOL kids, you can tell -- right?) The song refers to guys in heat wanting to scratch a cat, or a pussy to be more exact.
You can guess what heat they're in and exactly which pussy they're talking about. (I don't know anything about the 10yo kids they're mentioning.)
I'm sorry to tell you since you didn't know that, you're even less COOL than I am. Keep up with the times, dude!
