urbandictionary explains "opposite sex" this way
The opposite of sex (i.e. World of Warcraft).
John: Hey dude, did you have teh sex on the weekend?
Melvin: No, I had opposite sex.
John: You mean Wow?
Melvin: Yes, shut up.
I don't really understand that explanation. I know World of Warcraft is a massively multiplayer online role-playing game by Blizzard Entertainment. Does that explanation means that popular game is the opposite of sex?
It seems quite different to the meaning in other dictionaries, such as
merriam-webster: the people who are not the same sex
collinsdictionary: If you are talking about men and refer to the opposite sex, you mean women. If you are talking about women and refer to the opposite sex, you mean men.
Could some help me on this?
