then the person would go home to find that it is nothing

Vinegar Strokes 

An old and very descriptive scouse expression depicting male masturbation.

Like the pouring of vinegar on fish & chips, with the bottle and it's bulbous head pointing down the vinegar bottle is shafted repeatedly in a downwards motion to release a tiny squirt of vinegar on every thrust, much like the male orgasm at the end point in which ejaculation is inevitable, coincidently producing a scrunched up face similar to one that has just sniffed vinegar.

Dave: that wank I had last night was lush
Paul: did your face scrunch up when you started on the vinegar strokes?
Dave: aye, it was like being in a chip shop

Vinegar-Stroke Checks 

In chess, a computer's meaningless checks just before mate are called 'Vinegar-Stroke
Checks'.

Checkmate is totally unavoidable - all black has left are the meaningless vinegar-stroke checks.
