Quoted from Deaconblooze:I watched my sister-in-law's mma dbag boyfriend attack some poor unsuspecting bastard holding her hand at her twin sisters wedding. Just snuck up behind him like a real tough guy, slip, and bam, guy was out and dropped. He fell and hit his head on concrete, and got a subsequent concussion from that.
And congratulations are in order, they're now engaged!!
Who's engaged? Your sister and the mma dbag? Your sister and the unsuspecting bastard? The mma dbag and the unsuspecting bastard? Your post is ambiguous.
