【ALL OUT: AJ RAVAL】

College students everywhere are ALL OUT: AJ RAVALsaying cheers to a man they probably didn't know. But they certainly knew his famous invention, usually found by the beer keg or on the beer pong table.

The man who invented the red Solo cup, Robert Hulseman, died on Dec. 21, and in recent days tributes have been flooding in on social media. He was 84.

Hulseman invented the ubiquitous red party cup in the 1970s. His son said in reports that the cup was supposed to be for families to use, but his father didn't understand how popular his product was in the party scene -- especially on college campuses.

This one woman apparently used the cups as the inventor intended. She seems to be the only one.

In Hulseman's obituary in the Chicago Tribunethat ran in the days before Christmas, his family wrote that the inventor of the cup and those helpful Traveler Lids for hot drinks on the go was more than just his job, he "was known for his sense of humor, which manifested in many a bad joke, great wit, and his ability to spin a partner on the dance floor" and his love of music.

Seems fitting then that his death has also renewed interest in country singer Toby Keith's 2011 song "Red Solo Cup," which is all about the party culture that grew around the product.

Cheers.
