It is 9:00PM, one of my coworker said to me:"Dude, keep it real..".
I am curious about what does that means? I thought that phrase only has negative meaning( like true to urself. behave your true self, etc.. I can not find any positive meaning about this phrase), so I am wondering does he just tell me to relax and chill( be a REAL human and do not push myself unrealistic hard, because I started work from 8:30AM to now) or this is a ironic joke( like he does not believe I am working but just wasting time pretending working)?
Since He said that directly to me, so this makes me so confused! Im still learning English, and I do not make any misunderstanding to anyone or by anyone, please help.
