Langer is Dublinese - see the film version of Roddy Doyle’s The Snapper. In an effort to hide the real father, the expectant daughter tells her father she had a fling with a Spanish sailor. The father tells his mates in the pub (the best scenes are the mates in the pub slagging each other) and one of the mates says - a Spanish Sailor, I bet he had a hefty langer on him.
(But in Cork langer is a gobshite😁).
Also, Saturn is the nearest planet to Uranus. If you sat on an urn you’re likely to swivel?
