Bizarre, fantastic, grotesque, weird share a sense of deviation from what is normal or expected. Bizarre means markedly unusual or extraordinarily strange, sometimes whimsically so: bizarre costumes for Mardi Gras; bizarre behavior. Fantastic suggests a wild lack of restraint, a fancifulness so extreme as to lose touch with reality: a fantastic scheme for a series of space cities. In informal use, fantastic often means simply “exceptionally good”: a fantastic meal. Grotesque implies shocking distortion or incongruity, sometimes ludicrous, more often pitiful or tragic: a grotesque mixture of human and animal features; grotesque contrast between the forced smile and sad eyes: a gnarled tree suggesting the figure of a grotesque human being. Weird refers to that which is mysterious and apparently outside natural law, hence supernatural or uncanny: the weird adventures of a group lost in the jungle; a weird and ghostly apparition. Informally, weird means “very strange”: weird and wacky costumes; weird sense of humor.
