This is one of the most mispronounced words in the English Language. It should rhyme with "coffin". It isn't "off-ten".

Person A: How off-ten do you read?
Person B: Apparently you read too much, since it is "often", not "off-ten"!
Person B: (writes "listen" on a piece of paper) How to you pronounce this word?
A: Listen. it has a silent T.
B: Then why do you pronounce it in "often"?

Jed says, "that's a 10-4, whats your 20"?

Bud: marker 27.

Jed: I got my eyes on.

Once too often 

If you do something once too often it means that you have repeated an action which is bad, stupid or dangerous with an unpleasant end result. So you end up looking a complete wanker, in A & E with serious injuries or someone is totally pissed off with you to an extent which is going to be detrimental to your health and wellbeing.

He’s pissed them off once too often, they’re going to put the fucker on crutches.
