Originating from a mountaineering slang - a climber following the leader on a steep slope would have to put-up with it if the person above needs to relieve himself.

Pissed off - an unpleasant experience that one cannot do anything about.

[Mark Zuckerberg]

Extremely powerful anger that builds up inside, and you constantly want to release it, but when you do, it unleashes a full wrath that might cause the biggest calamity that had ever existed... or
When you are pissed off at someone or something, that means that you are angry or frustrated at him/her/them/it for whatever he/she/they/it did to you, and you want to get revenge on him/her/them/it.
In other words, you are mad. I mean, really? Do you really need to look this up? Come on! Seriously?
