A wonderful "catch-all" notation that basically "lets you off the hook" and allows you to do whatever you please if all other parties involved agree to it.
One should be very wary about signing/agreeing to something that includes ", etc." at the end of a line, since this basically gives the agreement's profferer "carte blanche" or "the sky's the limit" permission to have/do whatever he/she pleases --- if someone squawks, he can always run back to that wonderful little "etc." word in da agreement and say, "Hey, you guys implied that I could do anything I saw fit, this is just one of those!"
A period of time that two friends allocate for doing homework together but that they use for discussing their (usually failing) love lives
"You up for some Math Etc. later? I've got Calc to do and she stood me up again today."
When you yell something you would not say on twitter but want to say anyway in a large group of friends.
Generally it is vulgar stupid or funny.
Dave:I just took a shit!
Mike: i am sick of your stupid Etc. Tweets just shutup!
ETC stands for *EVERY*THING*CREW* in Modesto California. It was created by three friends doing drugs in a garage on Christmas Eve of 2017 and is now a six man crew of brothers who are ready to go with the dumb shit to make sure that they're going to come out of any situation the victorious ones. They're not a gang or a tagging crew but it is a hobby for a couple members to spray paint a few walls around town with the name of the crew. Do to the fact that they are willing to do anything and everything that is needed to win and protect the ones they love and each other it's a unfortunate but a side effect of the willingness is going to jail or prison for the way they go any route to win and protect whether it is legal or not so it is a rare thing to actually see the ETC... six pack all together at the same time you are most likely lucky you don't because if you do it is most likely only getting worse for you
ETC... was stated on Christmas Eve 2017
Etc means everything cool
