Toxic Comparison

Alright listen up, nimrod. This joke is saying someone is more toxic than WHITE PHOSPHORUS! You know how dangerous white phosphorus is? It ignites spontaneously in air and is used in bombs and incendiary weapons! It can cause severe burns and organ damage when ingested or inhaled. Basically, it's BAD. So calling someone more toxic than white phosphorus is a HUGE insult, which I think is based.
