Cherub, to be used as a secret replacement for the word cunt on social media. When one has friends, family and colleagues on the same social media platform/s as their closet friends, to whom cunt is used frequently as punctuation or as a term of endearment, you replace cunt with cherub as not to offend anyone, but those closest to you know exactly what you mean.
"The kids wouldn't go to bed last night when we asked them too, bless the little cherubs"
