noun
male pretending to be female online
Internet slang; a man who presents as a woman in online communities, games, or social media. Often used in contexts like online dating, chat rooms, or MMOs. The term is a blend of ネット (net) and オカマ (okama, a slang term for a gay man or cross-dresser).
あのプレイヤー、実はネカマだったらしいよ。
That player was actually a guy pretending to be a girl, I heard.
ネカマに騙されて課金アイテムを送ってしまった。
I got tricked by a male posing as female online and ended up sending paid items.
Blend of ネット (net, from 'internet') and オカマ (okama, slang for a gay man or cross-dresser). The exact origin is uncertain, but it emerged in Japanese online communities in the late 1990s or early 2000s.
