‘Slapped’ Man Utd brutally trolled by Grimsby in meme craze after suffering shock Carabao Cup giant-killing in epic penalty shootout

The Red Devils headed to Blundell Park aware that a giant-killing in Cleethorpes could be on the cards. Ruben Amorim’s side have stumbled out of the blocks in 2025-26, with just one point being picked up in Premier League action.

With United struggling to get into the winning habit, they fluffed their lines again when facing League Two opposition. Said contest could have been over in 90 minutes, with Grimsby racing into a two-goal lead courtesy of some questionable goalkeeping from Andre Onana.

The Mariners also had efforts disallowed before seeing Bryan Mbeumo and Harry Maguire complete a late comeback for United that forced the tie into a penalty shootout. An epic battle of nerves from 12 yards eventually finished 12-11 in favour of the hosts - with Mbeumo crashing the decisive spot-kick against the crossbar.

Wild scenes of celebration were sparked in North Lincolnshire, as fans invaded the pitch, while United were left to reflect on another humbling setback. Grimsby poked fun at the top-flight giants on social media by posting a “You’ve just been slapped by the fish” meme.

Said response to victories has become increasingly popular, with humorous and often bizarre memes being used to remind rivals of what they have just endured. United face a tough run after the September international break, which they will head into after welcoming Lancashire neighbours Burnley to Old Trafford on Saturday.
