When a person inserts a Baked Potato in their rectum, and someone else gives them anal sex. The Potato becomes mashed and then the person promptly shits out the mashed potatoes into the other persons mouth.
"Yo Nick my girl just gave me an IrishSteamroll how awesome is that"
A sexual act in which one makes a potato dildo, dresses up as a leprechaun, step dances around their partner, pores Guinness on the partner and fornicates with them.
The most aggressively Irish sex move ever conceived by a man who has already lost an argument with gravity. After approximately 9–14 pints of the black stuff, the lad decides the night needs one final, unforgivable flourish. He grabs the nearest spud (usually a decently-sized rooster potato he was saving for Sunday dinner), gives it a quick “God bless ya” kiss for luck, and — with the confidence only a blood-alcohol level in the triple digits can provide — attempts to full-send the entire potatostraight into his partner’s ass in one heroic, poorly-aimed thrust.
No lube.
No warm-up.
“Mate I gave her the Irish Rammer. Proper job. She’s walkin’ like she’s got a full harvest festival in there. Potato came out clean though — legend says if you boil it three times it grants wishes.”
An Irish intervention is when a group of friends get together to tell one of the group they're not drinking enough an occasion on which a person with an addiction or other behavioural problem is confronted by a group of friends or family members in an attempt to persuade them to address the issue.
We had an Irish intervention for Ben he's just not getting through his 12 Guinnessper night out.
