Everyone/ Everything is cool.

Whoever you are/ Wherever you're from, you're alright with me.

Despite any possible doubt, everything's cool.

Means nothing is bad.

Used in an optimistic sense to show the lightheartedness of something.

Platitude that covers so many emotions and situations that it says little; its only real meaning is that the speaker is trying to rise above whatever problem exists, without expressing their underlying negative emotions. (They might be angry, sad, upset, frustrated, hurt, disappointed, etc.) Often used in a passive-aggressive way. Rarely, used compassionately for someone else, trying to make them feel better. A favorite of inarticulate teens; fills in the gaps between: like, dude, dudette, whatever, so, I dunno, hey, etc.

“Its all good” means: You've just fucked up beyond all comprehension and belief , I'm never speaking to you again.

I have nothing to say other than a meaningless platitude.

A phrase popularized by MC Hammer himself and used as the title of many songs since.
