Standing Operating Procedure (SOP) - Commonly and erroneously referred to as Standard Operating Procedure. Written military directives defining the actions to be taken upon the occurance of specific events.
In the event this unit receives female soldiers, SOP requires that the showers be monitored by the senior NCO. If the senior NCO is male, sunglasses will be issued to him by the Charge of Quarters.

Someone who is soppy: overly emotional, overly romantic, and generally being a wuss. You wouldn't call yourself a sop, you'd call someone who wasn't being hard enough one. Commonly used in the UK.

Homer Simpson's misspelling of the word 'stop'.

In the Simpsons Movie, when Homer located the truck in which his family was being held, he made an attempt to hold the truck off for a moment, using a red hexagon (as opposed to an octagon) with the word 'SOP' sloppily painted on it. But as with almost anything that Homer does, it actually worked.
