Why Idioms, Slang, and "Gonna" Are Quietly Costing You the Room

Idioms, slang, and colloquialisms have their place in presentations, but each one deserves careful consideration. As more associations host virtual events and conferences with international or regionally diverse attendees, the potential for language to confuse, alienate, or inadvertently offend has never been greater. Here is what to watch for.

Idioms

Idioms are expressions whose meaning cannot be deduced from their literal words. They are deeply regional and generational, which means the larger or more diverse your audience, the greater the risk.

I learned this firsthand. While presenting to a group from China, I used the phrase "the grass is always greener on the other side of the fence." Afterward, a woman in the audience approached me and asked what it meant. When I explained, she smiled and said, "Oh … it is like saying the moon is just as round here as it is in their yard." Same concept. Entirely different expression. And had she not asked, she would have been confused for the rest of my presentation.

Common idioms like "hit the ground running," "bite the bullet," or "under the weather" can trip up listeners who did not grow up with them. Check your presentations for idioms and replace them with direct language.

Slang

Slang presents similar challenges — and often more than speakers expect. Terms like "ghosting," "low-key," "circle back," or "bandwidth" (used to mean capacity rather than internet speed) are now common in many professional environments but entirely opaque in others. When in doubt, say what you mean plainly. Clarity is always more professional than cleverness.

Colloquialisms

Colloquialisms are informal expressions that most audiences understand, but that may not be appropriate in every setting. Words like "gonna," "wanna," or "kinda" are fine in casual conversation but undermine credibility in formal presentations. Your word choices signal how seriously you take the occasion — and how seriously you take your audience. That said, colloquialisms can occasionally be used intentionally for effect. Pick your signal with intention.

Geography Creates Meaning

In the United States, "suspenders" hold up trousers. In England, the same word refers to lingerie. In England, "braces" hold up trousers — in the U.S., they straighten teeth. In German, the word 'Mist' means manure. More than one American speaker has tried to compliment a morning view and accidentally praised something else entirely.

When you speak to audiences from different regions or countries, do your homework. A few minutes of research can prevent a moment that derails your credibility and your message.

The goal of every presentation is to be understood completely, accurately, and without your audience working to decode your words. Clear, direct, audience-aware language is not a limitation. It is a superpower. Use it.
