Renob is boner spelt backwards. Many people thought and still think that it means the same thing as boner. but with my degree in ancient language from Harvard and extensive knowledge of a thing called "Mathematics" i've been able to understand that renob= -boner. and as we all know a negative boner is when something is so f@#king gross that it makes your penis deplete in size.
1) dude, have you seen that new chick. danm shes ugly.
2) yeah man, she gave me a massive renob!
