A naval term used as an excuse by somebody who stumbles into the back of another person, often when the penis of the stumbler is in a somewhat turgid state. The stumbler is blaming the way the
ship is rolling about in what is probably a heavy sea.
The usual response to that involves a roll of lino. That is a comparison with a roll of linoleum floor covering, i.
e. something
hard,
thick and
long. That may be a warning to not do it again, or a thinly veiled invitation to do it again, only more deliberately. Nobody knows which is which until they respond in the wrong way.
Jim Lad: "What the fuck was that???"
Nobby: "Sorry, roll of the ship"
Jim Lad: "Felt more like a roll of lino"
Nobby: "Oh, interested?"
Jim Lad: "Go and fuck yourself"
