This week, he and several other NFL players were taken to task by a class of second graders, who spent a lesson correcting the error-laden tweets the ball players posted on Twitter.
Blowing up copies of the offending posts, they circled the errors in red marker and wrote revised versions of the original messages underneath.
New England Patriot Wes Welker and Titus Young from the Detroit Lions joined Culliver on the students' list of poor spellers.
Some tweets were so indecipherable that even after the children had corrected the spelling and grammar, their meaning remained unclear.
Culliver's week went from bad to worse on Sunday after a terrible performance in the first half of the Super Bowl.
The cornerback was already in the public's bad graces after making anti-gay remarks during a podcast interview.
'I don't do the gay guys man. I don't do that…’ he told radio host Artie Lange. ‘We don't got no gay people on the team, they gotta get up out of here if they do.’
Following a huge public outcry, the 24-year-old Philadelphia native issued a bizarre, rambling apology.
Culliver's publicist has said that he will work with The Trevor Project in the weeks after the Super Bowl to learn more about lesbian, gay, bisexual and transgender youth.
