#5 WWE file trademarks

WWE has filed trademarks for four different catchphrases recently, as per PWInsider. They have filed two trademarks relating to Bray Wyatt's gimmick - "Yowie-Wowie" and "Firefly Funhouse". The other two are Sasha Banks' "Legit Boss" nickname, and Braun Strowman's "Monster Among Men" nickname.
These trademarks have possibly been done so that WWE can use them on merchandise and promotion, and ensure that no one else uses them.
