twitterati.club, I own this domain name, Is this a trademark infringement?

Hello,
I own the following name twitterati.club.
Twitterati means "keen or frequent users of the social media website Twitter", for example:"no celebrity member of the Twitterati seems to have caused as much of a splash as has Stephen Fry"
I am concern that I may be slapped a notice for trademark infringement from Twitter.
Please advice.
Thank you very much.
Haroon
