Is it okay to refer to yourself as Nak Muay?

I train 3-4x a week, but I’ve no intentions of going pro or possibly even doing amateur bouts at this age I’m at (32m), but I know others who still compete at my age. I’m just a father of 4 that loves the lifestyle, and strives to learn and execute each day. I’m just not certain if it is acceptable to have that labeled or not. I thought it would be neat to add that to my username, rather than MuayThai at the end on Instagram etc. I just enjoy training so much and think it’s so cool. But I don’t want to seem like a fraud or weird?

Edit: I apologize for ruffling any feathers. I honestly just wanted some clarity whether practitioners were labeled any differently than the pros. Thanks for the input given.
