slop (n.1)

c. 1400, "mudhole, puddle," probably from Old English -sloppe "dung" (in plant name cusloppe, literally "cow dung"), related to slyppe "slime" (from PIE root *sleubh- "to slide, slip").

The meaning "semi-liquid food" is by 1650s; that of "refuse liquid of any kind, household liquid waste" (usually slops) is from 1815. The meaning "affected or sentimental material" is by 1866.

slop (v.)

"to spill carelessly" (transitive), 1550s, from slop (n.1). The intransitive sense of "be spilled or overflow" is from 1746. Related: Slopped; slopping.

slop (n.2)

late 14c., "loose outer garment" (early 14c. in a surname, sclopmongere), of obscure etymology, perhaps from Old English oferslop "surplice," which seems to be related to Middle Dutch slop, Old Norse sloppr (either of which also might be the source of the Middle English word), perhaps all from Proto-Germanic *slup-, from PIE root *sleubh- "to slide, slip" on the notion of a garment one "slips" on or into (compare sleeve).

The sense was extended generally to "clothing, ready-made clothing" (1660s), usually in plural slops, also a nickname for a tailor. Hence, also, slop-shop "shop where ready-made clothes are sold" (1723).
