So “Hormussy” would be a meme-ified version of Strait of Hormuz, which is often in the news because of geopolitical tensions involving Iran, oil shipping routes, and naval activity.

In that context, “open that Hormussy” would most likely mean:

an intentionally absurd, edgy meme phrase referring to the Strait of Hormuz, using sexualized slang (“-ussy”) to turn a strategic chokepoint in global oil shipping into internet humor.

So the joke structure is:

Hormuz (strait) → “Hormus-”

internet suffix “-ussy”

→ “Hormussy”

then “open that…” as a meme-style command phrase

Meaning in plain terms

It’s essentially:

irreverent meme humor about the Strait of Hormuz, a major geopolitical oil chokepoint, phrased in deliberately absurd sexualized slang for comedic shock value.

Why that specific reference works as a meme

The Strait of Hormuz is:

globally significant (oil shipping chokepoint)

frequently associated with geopolitical tension (Iran, U.S. Navy, shipping security)

So it becomes “memeable” in the same way other high-stakes geopolitical names get distorted online:

serious → abstracted → stylized → absurdified

Tone of the joke

This kind of phrase sits in:

ironic internet humor

geopolitical meme culture

“everything becomes -ussy” meme format

erything becomes -ussy” meme format

It’s not meant to be literal — it’s a distortion of a real strategic location into absurd slang for comedic effect.
