Rump raid is a slang term for an anal sex encounter. The term comes because rump is a synonym for the buttocks, and a raid is an assault or an attack on something, in this case the rump. People who engage in anal sex are sometimes called rump raiders, an appropriation of this term.
More About Rump Raid
Rump raid isn’t a mainstream term, but it tends to be used in some subcultures and the porn industry.
If you intend to have a rump raid, it’s important to remember that the anus is not naturally lubricated. Thick lubricants like KY Jelly are advisable as they don’t dry out as quickly as water-based lubricants. It’s also important for the person whose rump is being raided to relax the pubococcygeus muscles at the anus as much as possible for easier entry.
Safe sex is crucial during a rump raid, even among monogamous couples, as it prevents bacteria from the bowels spreading and infecting other areas. You should never use the same condom for penis-in-vagina sex after a rump raid. It’s also advisable to keep some baby wipes close by to clean off or have a shower after a rump raid.
