Not bad (2/5), the reason of this rate being low is that it doesn't offer much creativity and space for enthusiastic philosophers. If you want to base your nickname on a common word, that word should be slightly changed or largely, change the spelling or add something else to it without losing the original meaning/add more to it ;)
Okay (2.5/5), similar story, it's not so-well known in usage word but it's being combined by two very different yet very popular words. I wouldn't ever guess what you want to say by that name, playstyle in games could be my guess with a 100th time but it sounds good so that adds from me to it. Not bad overall.
barfite (as suggestion, slightly changed spelling for 'g' pointing down kills the beauty of nickname, letters should be up. Relatively the same but with a better looking lineup ;)
