A man at a Colorado Avalanche game elbowed his girlfriend in the head trying to catch a puck ... and then gave the souvenir to another woman -- and his GF was PISSSSSEEDDD!!!!
It all went down at the Avs-Jets game in Denver on Wednesday night ... when Colorado star Gabriel Landeskog flipped a puck in the stands to give fans a shot at some memorabilia.

That's when a guy committed the ultimate dating foul -- not only catching his GF with a flying 'bow .
