April is when baseball starts; Anglesault's trademark, so to speak, is his fanatical love of the New York Yankees, which resulted in him going nuts after every loss. He also hates Edge, Orton, and hip-hop culture, but so do I, so that's not as crucial.
PBP means previously banned poster. The rule is that if you're banned, but find a way to weasel back in, any suspicious activity will make the mods check IPs and ban you again if needed, even if you didn't officially break a rule. This rule is enforced veeeeeeeeeeeeeerrrrrry subjectively.
