A person who promotes, sells, or exaggerates the deeds of heroes, similar to a fishmonger selling fish.
Combines 'hero' with '-monger' (from Old English mangere, a merchant or trader), using the suffix that also appears in 'warmonger' and 'fishmonger' to suggest someone who peddles or traffics in something.
The '-monger' suffix is one of English's sneakiest ways of being insulting—calling someone a 'heromonger' suggests they're not genuinely celebrating heroism but commercially exploiting it, which is why we use it for warmongers, fearmongers, and gossips.
