One who does you a favor. Antonym of backstabber
Dude you left your keys at my apartment last night. Here you go.
Oh, thanks.
Yeah I also took the favor of carrying your recycles outside.
Wow you're such a frontstabber!
Did that acid wear off yet?

Get the frontstabber mug.
Someone who's up front about putting their knife between your ribs.
He/she was a frontstabber, so having your back turned wasn't the only time to be aware of what he/she was doing.
