A lazy way to compliment a local band at a gig so that you can ignore their set or otherwise not bother to think of something original to say. This phrase is prevalent in the Ottawa music scene and is interchangeable with "Cool set, bro" and the even more unintelligent "Ayyyy yo that set was fire, fam!" This phrase is used mostly by pop punk, emo and "hardcore" music fans. Sadly, the most common response to this phrase is "Lol thanks, we actually fucked up a bunch of times though."
Scene Kid: Sick set, bro!
Band member: Yeah. Thanks for completely ignoring the time and money we put into writing and recording our songs. Why are you here?

Actually, this saying is ITSELF one of the LEAST “true” statements of all time… as we are all too painfully aware, “coming clean” to the powers-that-be (i.e., parents, teachers, policemen, etc.) seldom if ever actually gains or maintains your “freedom”; in fact, usually the **exact opposite** occurs whenever you bravely/penitently reveal your shameful secrets like this --- rather than their extending any significant “charity” (i.e., mercy or forgiveness) to you in response to your trustingly/naively-admitted revelations of past transgressions, these hypocritical and out-of-touch-with-reality sadists generally do everything they can to CURTAIL your freedom and otherwise make you as miserable as possible, such as giving you an extended time-out, grounding you for an outrageously-long period, making you stay in from recess, throwing you in the slammer for a few days, and so on. So unless there is some serious injustice that your silence is maintaining (such as that an innocent person is being blamed/punished for something that you did), it’s usually wise to follow Will Roger’s advice to “never pass up a good chance to shut up”… contrary to what these authority-figures may try to assure you, they generally do **not** “have your best interests at heart”… about all they actually wanna do is try to soothe their **own** perpetually-gnawing consciences by being overly hard on anyone under their care!
My conscience was pricking me after hearing the local minister preaching about “the truth shall set you free”, and so like the total dumba** that I am, I went to the police station and admitted to the desk-sergeant about my having swiped a few candy-bars and a couple bottles of soda from the local Circle-K over the past six months; rather than just smiling and praising me for “being a good boy” to be so honest, though, the officer merely slapped da cuffs on me and made me cool my heels in jail for 48 hours! Talk about a letdown --- he didn’t even seem to care about my protests that he was blatantly going against what the preacher had just said was supposed to happen when we admit our sins! I think I’ll sue that minister for misrepresentation and deceitful speech --- I shoulda merely kept my big mouth shut, just as I always have in the past regarding stuff like this! And then he wonders why he has such a hard time gaining or keeping church-members!
