A haggidy it's a guy that does what he wants. He truly gives no f***s.
When walking on a busy high street, if he wants to randomly sit down in the middle cross-legged, he will and won't say a word to you, and you will keep on walking on until you realise he is not by your side.
A haggidy type of person can also be nicknamed "haggz" or "haggidy bhagwan"
