History
Etymology
Originally referred to a slow, lazy person, from Middle English slugge (“lazy person", also "sloth, slothfulness”), probably of either Old English or Old Norse origin; perhaps ultimately from Proto-Indo-European *sliǵ-ōn, from *sley- (“smooth; slick; sticky; slimy”) or otherwise from the root of Old Norse slókr (“lazy person, oaf”), whence Icelandic slókur (“laziness”). Compare Norn slug (“lazy, slothful, sluggish”), dialectal Norwegian slugg (“a large, heavy body”), sluggje (“heavy, slow person”), Danish slog (“rascal, rogue”). Compare also Dutch slak (“snail, slug”). Doublet of slotch. The sense of a hitchhiking commuter is from the sense of a counterfeit bus token. Bus operators considered sluggers to be cheating as if they were using counterfeit tokens.
Uncertain. Perhaps somehow from Proto-Germanic *slagiz (“a blow, strike”). If so, then cognate with slay and slaughter; also German Schlag (“blow, hit”) and Dutch slag (“blow, strike”). Also compare slog.
