KANSAS CITY, Mo. (KAKE) - A new study has found that out of all 32 NFL teams, the Kansas City Chiefs fans complain the most about officiating on Twitter.

The study, put together by Bet Online, uses Twitter data from week 1 to week 10, tracking negative fan tweets about NFL officiating for each team. 

They say that to find out which fanbase complains the most, they looked at the total number of fan tweets (in general) and then determined what percentage of those tweets were complaints about refs.

They singled out phrases like "bad call," "horrible call," "bad officiating," "horrible officiating," "missed call," "horrible refs," "refs beat us," "refs screwed us," etc.
