Squeeze Theorem/Also known as

Squeeze Theorem: Also known as
This result is also known, in the UK in particular, as the sandwich theorem or the sandwich rule.

In that culture, the word ' traditionally means specifically enclosing food between two slices of bread, as opposed to the looser usage of the ', where the there is only one such slice.

Hence, in idiomatic British English, one can refer to the (often uncomfortable) situation of being between two entities as being sandwiched between them.

As the idiom is not universal globally, the term squeeze theorem is preferred on, for greatest comprehension.
