For wackier definitions and slang, I like UrbanDictionary. I’d say Wiktionary, but someone already suggested that one.
I’ve also used dictionary.com and thesaurus.com in the past. Obvious names, but they’re not terrible.
But back to UrbanDictionary - there’s a lot of craziness and dross on there, but there are also plenty of diamonds in the rough.
I’m not sure that counts, considering which subset of the population is the largest consumer of it. That in and of itself doesn’t make it fail*, but the fact that the makers of it know this and thus might be tailoring it for that audience does kind of make the the whole thing about men.
Basically, we’re just swapping one meaning of intercourse for another.
* in the same way a group of men watching a regular movie that passes the test wouldn’t change that fact.
