Why the Phrase “Culo e Camicia” Exists
Do you know why people say “those two are, so to say, butt and shirt”? It’s a popular saying whose origins are much more intimate than one might think. We are talking about the period before underwear existed. The word “camicia” comes, on one hand (from Latin), meaning the thing that must be changed — understood? Because not everyone… Anyway: before underwear, shirts were much longer than those of today. They reached down from the knees, because they served also to cover everything, you know, the necessary, the intimate parts.
So in fact, rather than “butt and shirt,” it was really “butt in shirt.” And thus, after a few days of wearing that shirt, it became one single piece with the… well, let’s say, it became very sticky.
Therefore, being “butt and shirt” meant being inseparable, always together. They were two friends who, no matter what, stayed together. And even when the situation stank, wherever one went, the other went too.
The Modern Meaning: Inseparable Friends
Today, saying two people are “butt and shirt” (i.e. “culo e camicia”) means they’re inseparable — friends who do everything together, or people with total complicity. It’s a metaphorical way to express a relationship of extreme familiarity, intimacy, or complicity. paroladelgiorno.com+2abcschool.com+2
Thus, the old, somewhat crude — even biological — origin has transformed into a colloquial idiom about bonds that are tight and lasting.
Historical Origins and Linguistic Roots
- The expression is said to trace back to times when underwear was not in widespread use. Shirts were long and worn directly on the skin, and often reached down to cover the butt. This close contact between body and garment was the metaphorical basis for the phrase. Qdpnews+2Learn Italian from Home+2

- Sometimes the phrase can carry a mildly ironic or negative nuance: implying not just closeness, but maybe complicity or over-familiarity, even suspicion when two people appear too united. Donna Glamour+1
