It refers to the act of giving yet providing nothing of substance in return, as it is named after the parasitic organism a leech.

Leecher can be applied practially to peer to peer file sharing protocols, or networks (Bittorrent, Kazza Fast Track, Gnutella}, in which the leecher consumes bandwidth by downloading, yet has no will to upload or give back to a community.

Particularly in Bittorrent, leechers are not actually increasing their performance, but possibly are decreasing it.
I know a leecher who in order to acheive maximum network thourough-output restricts uploading while bittorrenting.

Party Leecher

Someone you don't want to come to your party and purposely don't invite, but that you also don't want to tell they can't come. That person finds out about your party through the grape vine and invites themselves and does inevitably show up. The chance of the party being ruined is also significantly increased by this persons presence.
The Party Leecher calls you a few days or a week before your party to talk about something and then before hanging up says, "So I heard from (insert any name)'s brother that you are having a party. What should I bring?" You've just been, Party Leeched.

Aubs: "The fuck is that faggot doing here? He ruined the party." Jay: "I didn't invite him, he found out from someone else. And I can't tell him he can't come." Aubs: "Classic Party Leecher."

A leecher is a person on some type of internet community (torrent, forums, ect.) who downloads as they please and never contributes back to that community. Often characterized by low post counts or having nothing in their shared folder. Leechers steal a network's bandwidth with downloads and potentially can cause it to lag. Derived (obviously) from the parasite with many similarities to a Leecher.

Tom Leachery 

Derived from the term TOM FOOLERY.
TOM LEACHERY (AKA TOM SPONGERY) is the act of imposing excessive dependence on ones parents, siblings, coworkers or friends. Usually a behaviour committed by adult males between the ages of 21 and 30. These grown men refuse to leave the safety and security of their parents home - preferably the basement.
The allure of unlimited high-speed internet, free room, hot meals and a complete lack of real world responsibility is often too much to resist.

This act of Tom Leachery is (in best cases) ignored and (in many cases) despised by the subjects peers. Peers that are forced to live within the daily of confines of a 'normal' adult life: Mortgage/Rent, Car Payments, Marriage/Relationship, Children.

Adults committing acts of Tom Leachery enjoy numerous benefits including; increased cash flow, reduced stress, adequate sleep and a complete inability to sympathize with the their more 'responsible' counterparts.
What's with him these days? He's bought three bikes in the past month and damn he's gotten fast.

What do you expect? The biggest concern he faces each day ranges from 'did mom wash my underwear' to 'will dad leave enough gas in the Camry'.

I know, we can't be the only ones sick of his Tom Leachery...anyone call his parents?

fache-couture 

French slang, which translated, means "bull's fashion" but basically equates to "hyper trendy" or overly trendy. Used when a person wishes to express distaste at the latest fashion trend/fad, because it seems that everyone has a certain item of clothing or is wearing it.

A slang term for GLP-1 medications(like Ozempic, Wegovy, Mounjaro, etc.), usually referring to their appetite-killing, weight-loss, or “I forgot to eat” effects rather than the medical details.

Usage:
* Often casual, ironic, or meme-y
* Can imply effortless weight loss, suppressed hunger, or being “powered by pharmaceuticals”

Notes:
Not a brand name—just shorthand for the whole GLP-1 wave. Frequently shows up in online jokes, gym talk, and group chats where people pretend they’re *totally* doing it naturally.
“I’m not dieting, I’m just on that glippy.”
“Ever since the glippy hit, food feels optional.”
“That summer body? Yeah, glippy assisted.”
