Besides pregnancy as the worst STD, gonnasypherpelaids is the grand daddy combining gonorrhea, syphilis, herpes, and AIDs

gonnasypherpelaids = gonorrhea + syphilis + herpes + AIDs

Also, a hit-single by the infamous band Pig Mutilator (my former band)
Dude, that chick is nasty as shit. She's probably got gonnasypherpelaids.

Sebastian: Damn! I hooked up with that whore down the hall who got tag-teamed last week.

Julio: Yo man go get yourself checked for gonnasypherpelaids!

Jul 12 Word of the Day
The horrible moment when you realise that you have accidentally done something very slightly wrong which has very bad (usually embarassing) implications for you. This is typically the moment of realisation that you just sent a dirty text message to a close member of family, typically your mother, rather than the intended recipient.
Message: "i'm free this afternoon so come over and fuck me senseless, my parents will be out all day"
Recipient: Mum
