Ripping and dipping is a prison term indicating a fast and furious raping, typically involving ripping off a prisoner's clothing and then "dipping", a euphemism for the act of anal sex.
Sometimes this can be used as a crude way to describe a violent quickie.
You know what they do to punks like you in jail?! With that pretty face? You'll be two days in general population before they rip and dip you.
When you see someone and they're super hot and you have to fuck immediately. But once it's done you've lost interest as the lust has gone or the sex didn't live up to the expectation for example.
"So are you attracted to him?"
"It's not quite the rip your clothes of immediately lust that I get occasionally with some guys"
"So its just a rip and dip situation?"
Rip and dip friends are one of those friends who would talk to you for a brief period of time and after would disappear from existence. Sometimes they will return to talk to you again briefly so they can be entertained for a bit only to disappear once again.
This usually happens online if you do not talk in person or on the phone on a regular basis. This doesn't exactly mean they are bad friends, just ones you can't be extremely good friends with.
