When someone you thought was your friend turns around and fucks your wife when you're out of town, and then claims that 'it just happened' --- for three years!

When you eat dirt for the first time and leave your family to build a shack in the woods

When you have been betrayed someone that seemed loyal has gone against ur will and stabbed you in the back.

The feeling you get when your at a party and everyone is quite the drunkness and the guy you have crushed on for ages is there and your 'friend' goes to find him to bring him back to you but doesnt end up doing that, so you go looking for her but then you find her making out by the fire with your crush...

1) when someone who is your "friend" finds it their place to hang all over your ex boyfriend;who you still have VERY strong feelings for, and everyone pretty much knows that.
2) When your "friends" put dicks before their chicks (best friends)

Betrayed is when someone who you really thought was a great friend that you've known for a while, goes and fucks you over. And by fucking you over i mean he drugs you just to get a good laugh; slips something in your drink when you are already a goner. Then he just leaves you their to fucking rot. You wake up the next morning missing your underwear and not knowing WTF happened, but you know it was all him. This is when you realize that you have been betrayed.

fucken when ppl hu call themselves ur "friends" wanna be fuckheads and make up shit to chics and other ppl so they dont like ya. ppl like this should have spears thrown into their face by Peter. See GroinKing
