Camp
Etymology
The aesthetic sense was fixed by Susan Sontag’s 1964 essay "Notes on Camp," though the slang is older. Its origin is disputed — one popular guess links it to French "se camper" (to posture flamboyantly). It began in queer subculture before spreading to the mainstream.
noun · /KAMP/
A sensibility that finds delight in the exaggerated, artificial, and gloriously over-the-top.
What it names
A way of loving something precisely because it is too much — theatrical, ironic, and knowingly tasteless.
Example
The movie’s giant rubber monster and painted backdrops were pure camp, and the audience adored it.
Related idea
Camp overlaps with kitsch but points the other way — kitsch is bad taste taken sincerely, while camp is bad taste embraced with a wink.
