# How every generation says that's hilarious

Calling something hilarious does more than report that you laughed: it tells the other person how hard it hit and whether they should take your reply as warm, dry, or nostalgic. Newer internet phrases lean on theatrical overload; older ones more often name the laugh or the good time itself.

Generation by generation

## Saying "that's hilarious" across the ages

1.  Gen Alphano word of its own

    Gen Alpha has not settled on a distinct, generation-only equivalent here. In texts and short-form video comments, speakers commonly reuse “lol,” the crying-laughing emoji, or a current internet reaction such as “IJBOL,” so the wording changes from one group to the next.

    “That dog just stole the sandwich 😭”

2.  Gen ZI'm dead

    “I’m dead” means “that was so funny I cannot cope,” not that the speaker is in danger. It is a strong, friendly reaction in messages and comments; it can also signal shock or secondhand embarrassment, so read the post it answers.

    “He sent the meeting invite to the whole company, I'm dead 💀”

3.  MillennialI'm dying

    “I’m dying” is a familiar hyperbole for laughing hard, often made fuller as “I’m dying laughing.” It remains natural between friends in texts and social posts, although younger speakers may choose “I’m dead” for the same extra-intense response.

    “You put the cat in a tie for the family photo? I'm dying.”

4.  Gen X[cracked me up](https://genzdecoded.com/dictionary/cracked-me-up/)

    “That cracked me up” says the thing genuinely made you laugh; it sounds conversational and less theatrically overwhelmed than the newer death metaphors. It still reads current in speech and writing, especially when reacting to a story, while “crack up” can also mean to begin laughing.

    “Your dad trying to use the selfie stick cracked me up.”

5.  Boomer[a gas](https://genzdecoded.com/dictionary/a-gas/)

    “A gas” calls someone or something very entertaining, usually in “That was a gas” or “He’s a gas.” It now has a deliberately old-fashioned, affectionate sound in American English; Dictionary.com labels the sense slang, so it lands best with people who know the expression.

    “Your uncle at the reunion was a gas.”

The through-line

## What they all have in common

All five choices turn laughter into a social signal: you are telling someone their joke landed and inviting the shared reaction. The differences are in intensity and age-marking, “cracked me up” reports a laugh, while “I’m dead” and “I’m dying” perform being overwhelmed, and “a gas” remembers a whole enjoyable person or occasion.
