(usually humorous) Forming nouns denoting a putative ability to detect a thing.
词源说明
Probably from rebracketing of gaydar, itself a blend of gay + radar. Alternatively radar might have been rebracketed directly as ray + -dar, but this appears less likely because rays are, if anything, that by means of which a radar detects things.
