Ryan Lochte's trying to trademark his catchphrase "Jeah!".

TMZ reports Lochte just filed documents to lock up a trademark for the made-up word.

The documents reveal that Ryan wants to use the word on sunglasses, workout DVDs, gift cards, mugs, drinking glasses, trading cards, calendars, posters, swimsuits, swim caps, sports hats, and water bottles.

Lochte's website is selling "Jeah"-themed tees, hats, and sunglasses.

According to a 2009 interview, Ryan got the phrase from rapper Young Jeezy, who uses a similar word "Chea!" in his songs. Ryan says he changed it a little to "Jeah!" and says it means something "good."
