赤あか烏帽子えぼし

noun

strange thing; eccentric taste; red eboshi

Literally 'red eboshi' (a type of court cap), but used idiomatically to refer to something odd or an eccentric preference. The connection may come from the unusualness of a red eboshi in certain contexts. The literal sense is included for completeness but is rare in modern usage.
