However, the game is noted for Sexual Themes and Partial Nudity.
I'm old enough to remember when calling a person a twink in video games was basically an insult because its calling someone "gay" and a twink considered the bottom of the community. Basically, it was calling cheaters and those who paid for boosts 'gay' as an insult. But being that Europeans and some other gamers were clueless about this insult they started to equate Twink not as an insult or slur, but rather as just a booster or cheater forgetting the original reason why someone was called a Twink. I remember when a gaming company who used to make cheats for the Codebreaker renamed their company Codetwink and went out of buisness because the owner didn't know at that time what the majority of people considered the term twink.
The problem is ERP as a term is what I would consider new. Most normal people or a lot of gamers might not understand what it is. The reason why staff and people on the forums on FFXIV know what it is, is because people in FFXIV are flagrant with it and popularized it. In the forums a year or two ago when staff started banning and suspending people there were posters here condemning staff for not accept people and guilds who ERPG for Gil.
Back in the days when World of Warcraft was popular before CATA ruined it someone who was offering special services in the tram was called a hooker or prostitute.
Also the grand majority of people in the NA in fact 99.9% of us don't know what the word Bollocks is and will never care to. All we know is when we see weird people saying Bollocks this and Bollocks that they are foreigners. Which is why I recommend separating forums due to the fact there is cultural and regional differences and there are slangs that never of us understand. Most likely the word Twink was taken from Europeans who didn't know it was used as a gay slur to insult cheaters and they just took it as just a regular insult not understanding the meaning of cheaters.
