Why was "tantrum" trending last week?
1713, from shell (n.) + lac (see lacquer). Translates French laque en écailles "lac in thin plates."
1876, from shellack (n.). The slang sense of "beat soundly" is 1920s, perhaps from the notion of shellac as a "finish." Shellacked "drunk" is from 1922 (cf. plastered). Related: Shellacking.
Drunk: One of the boys got beautifully shellacked (1922+)
To pay; shell out: to shell at least a buck (1948+)
