You just change the above rumor sligtly!
Example:

Mewi1: I heard CK got a girlfriend!
Corruption: I heard CK got a boyfriend!
CK: I heard Corruption got a boyfriend!

So its a bit like change one word, exept with rumors and you can change more than one word.
And try not to say anything true -.-

So lets start :)

I heard Aragornbird got hacked!

I heard Aragonbid is back!

This totally won't go to shit. Why are you trying this if people will just get offended?
