While most of the US celebrated Fourth of July weekend with barbecues, pool parties, and various other patriotic activities, those in Los Angeles were able to attend the annual Anime Expo 2014, although their fun may have been slightly cut short by a certain Italian plumber with an evil death stare.

After the infamous "Luigi's Death Stare" took the Internet by storm shortly after the release of Mario Kart 8 back in May, a crafty cosplayer took Luigi's villainous stare and turned it into a clever cosplay, and an even more hilarious video.

Taken over the course of the weekend at Anime Expo 2014, YouTube user D Piddy's video shows Luigi "bringing chaos...and death stares" to the attendees of of the convention, lobbing green shells at them and giving his signature glare at the camera in hilarious fashion.

Anime Expo 2014 took place at the Los Angeles Convention Center from July 3-6, 2014 -- you can check out the full video below for a look at plenty of cosplay, and even more of Luigi's Death Stare:
