When someone says something offensive, inappropriate, or in any way goon-like, on Facebook Chat, and then immediately goes offline to avoid consequences of the comment.
A Hit and Run is a sure example that the offender has Bitch in the Blood as well.
Eno: Damn DJ, remember when I whooped you in NCAA Football last night?!

Facebook Message: Eno is no longer online, and the message could not be sent.
DJ: God bless, he just delivered a nasty Hit and Run!
