To be happy go lucky, is to be cheerful about most all things. To have a positive view on life. To annoy the shit out of your friends, and to just be a peppy shithead.

A person who is a pleasure to be around.
They dont sweat the small stuff.

They tend to laugh easily but not forceably so. They tend not to care about trival matters.
They are most always well adjusted and have no anger issues.

A term used to define a person who outwardly projects a calm and collected lifestyle, while inwardly is full of turmoil.

Having been privy to past wrongs the happy go lucky person refuses to impart that on anyone else.

This often comes across as a carefree individual, but is instead someone who cares deeply, and does not want to replicate the harm done unto them on anyone else.
After waiting for over an hour and a half in the crowded restraunt, the happy go lucky individual received luke warm food. Knowing the waiter had no responsibility for this, upon paying, the individual tipped over the expected amount, because they knew someone was going to under tip.

A description applied to an inexplicably happy or care-free, jobless, freeloading, sofa-surfing parasite who runs your bills up, eats your food then tells you how brilliant their day was getting drunk and stoned in the sun whilst you were at work.
A "happy go lucky" person always manages to find money for pot, beer and pasties for themselves (but not to replace items used) as well as someone else's sofa to sleep on, a fridge to raid and endless bottles of ketchup to consume...
The nicest thing I can say about Martin: he's happy go lucky.

Once upon a time, there was a man who had really swollen testicles. "Help me," he asked a crowd of elderly firefighters. "My testicles are really swollen, I'd appreciate it if you could recommend a topical analgesic that could make the pain a little less unbearable."
