From the New Oxford American Dictionary:

gin up
(gin something up, gin up something) US English generate or increase something, especially by dubious or dishonest means: the trade press has ginned up a controversy | critics say the program is just a way for big drug companies to gin up demand for their psychiatric drugs.
origin: Middle English (in the sense ‘a tool or device, a trick’): from Old French engin (see engine).

So it’s not an offensive slur (nor a reference to drunkenness), but it is an accusation of dishonesty that people would reasonably take offense at.

Maybe for the apostrophe abuse? It'd be "ginned" in English.

I had to go check, because I've heard a YouTuber use "gin up" a lot and they're not the sort to use slurs.

At time of writing Wiktionary's entry on "gin up" doesn't list it as a slur either, so I'm inclined to believe it isn't one.

What I think your employers / colleagues may have heard, or confused it with is "gip" / "gyp" (also soft 'g'), which is an abbreviation of "gypsy" and is generally used to mean "pain" or "a cause to complain", hence being a slur for travelling folk.

It's such a weak, ridiculous slur that many people don't even know its etymology and use it by imitation. It was very common on British TV up to the '90s, for example, and older British folk may still occasionally use it.

I hear it occasionally. Seems to have a meaning comparable to:

• Cobble together
• Jury rig
• Hammer something out
• Slap something together

Basically, "to construct something in an improvised manner". As opposed to careful, calculated, methodical planning and meticulous craftsmanship.

Sounds like you are call them alcoholic.

Isn't it a reference to making moonshine? That's how I grew up understanding it.

You didn’t do shit because you’re just reposting this from reddit.

Time to file a harassment claim against the other person for creating undue stress on your part because they chose to hear you wrong lol.

Perchance you slipped and meant to say G'd up?
