The New England Patriots pulled off a stunning upset over the Buffalo Bills on Sunday, and while the entire team celebrated, nobody had a more memorable reaction than the girlfriend of the game's unlikely hero.

Efton Chism III, an undrafted wide receiver from Eastern Washington, delivered the play of the game with 1:50 left in the fourth quarter. His one-handed, acrobatic touchdown grab gave the Patriots a lead they wouldn't relinquish, and the moment was pure magic for Chism and his loved ones.

Why Is Dan Quinn Still Employed? NFL Insiders Left Stunned
NFL insiders are baffled that Dan Quinn still has a job after Washington's clock-management catastrophe in overtime against the Giants. Adam Schefter and Rex Ryan predict consequences are coming.

Chism's girlfriend, Devynn Warns, was in the stands at Highmark Stadium, and her reaction was nothing short of electric. In a video she shared, Devynn is seen jumping up and down, screaming with joy, before letting out a hilarious exclamation: "I just peed myself!" The clip quickly became a fan favorite, capturing the raw emotion of a girlfriend watching her man shine on the biggest stage.

Patriots head coach Mike Vrabel was full of praise for Chism after the game. "Nobody works harder," Vrabel told WEEI. "You love to see players take advantage of opportunities and help the team win. He is very well respected. He practices. He is on the show team. He takes a million reps. Nobody logs more miles or yards or whatever we track than Chism."

Chism's journey to this moment has been anything but ordinary. Undrafted and overlooked, he's grinded his way onto the roster, and this game-winning catch is a testament to his perseverance. His teammates and coaches alike have rallied around him, and the locker room was buzzing with excitement after the win.

However, not everyone was in a celebratory mood. Bills defensive back C.J. Gardner-Johnson took a shot at Chism after the game, downplaying the achievement. "We're not going to get into any bulletin board material," Gardner-Johnson said. "An elevated guy made a heck of a catch — probably won't hear from him again. … A practice squad player made a heck of a play. That's all I'm going to tell you. You do it again, and he probably won't make it again."

Vrabel didn't shy away from the criticism, and the Patriots coach has been known to fire back at Gardner-Johnson's remarks in the past. The rivalry between these two AFC East foes is heating up, and the rematch is already circled on the calendar.

The Bills and Patriots will meet again on Dec. 6 at Gillette Stadium, and you can bet Chism and Devynn will be ready for another unforgettable moment. Until then, the internet is loving every second of Devynn's viral reaction, which perfectly sums up the joy of a last-second victory.

For a team that has faced its share of challenges against the Bills this season, this win was a statement. And for Chism, it's a night he — and his girlfriend — will never forget.
