Actual meaning- petty, insignificant, someone who is overly concerned with things that really don't matter outside of his or her own mind.
Example: a person could be considered "trifling" if they value money or superficial things that really are not important such as a gold digger or dudes who post handfuls of cash in their hands in a bathroom selfie to impress others when clearly the background of their selfie is a POScollege dorm type place they are living in with a broken shower head so it's obvious they are not really rich.
Another version is someone who makes a big deal out of things like not closing the blinds correctly or putting the toilet seat down.
A person can be called trifling as an insult as well because you are saying that they do not matter to anyone else but themselves, you are saying that they are unimportant.
My boss has gotten all worked up about trifling things lately, he posted signs everywhere that if the blinds aren't closed correctly or the air isn't on the exact temperature then you get blasted with some stupid email about it. It seems he really needs to find something in his life worth worrying about.
The textbook trifling bitch. You know, the one that cheats on you, snoops in your belongings, tells you how much she's not over you then immediately goes and sleeps with a married guy who's almost as old as my mom. Yeah, that girl.
A light or lazy version of masturbation, where one is not intending to finish the job. Mindless manipulation of the genitals while being preoccupied with other non-sexual tasks, often not even resulting in arousal.
Bill: "What are you doing, bro?"
Steve: "Not much, dude. Just watching the game and twiffling my junk."
Slang term for the underground practice of inhaling vapor from human feces, primarily for the narcotic effect of its methanethiol gas combined with the effect of hyperventilation. The term itself comes from "turd" and "huffing" due to the rapid inhalation and exhalation from paper or plasticbags containing the fecal matter. As with glue sniffing or hallucinogenic mushroom consumption,very unpleasant symptoms are experienced prior to the high, slowing the spread of the behavior. While its high is considered uniquely euphoric, tuffing is relatively brief and those who indulge in the practice risk severe infection, irritation of eyes and mucous membranes, convulsions or in extreme cases, coma or death.
Happy as they were, Shana and John annoyed all their friends after they'd been tuffing--they smelled like Mardi-Gras bathroom.
