One word cost Mark Cuban $30,000 during a celebrity "League of Legends" match at the Intel Extreme Masters in San Jose on Saturday.
The Dallas Mavericks owner dropped the f-bomb during an interview which resulted in the first $15,000 "fine" paid to CyberSmile.
"So if I say it again I have to pay another $15K?" Cuban joked during his post-game interview. (Warning: Video NSFW) When asked if he wanted to up his donation to $30,000, he dropped another expensive expletive with a smile.
The charity raised an additional $38,000 from the event.
This isn't Cuban's first foray into the eSports market. The entrepreneur invested $7 million in Unikrn, a Seattle start up that offers legal betting on competitive video game tournaments, according to Fortune.
