There was a kid in my class who said my face looked like a physical reaction (we were learning about that stuff at the time), so I said I made a chemical reaction with his mom last night.

Listen here, smartie pants. The joke is that the first kid insults the joke teller's face, saying it looks like a physical reaction. Then, the joke teller claps back with an even more disgusting insult, saying they had a "chemical reaction" (if you know what I mean) with the kid's mom. I bet you are still living in your mom's basement. What a loser!
