UDI

What Does UDI Mean in a Text?

The Quick Answer

A UDI (an Unidentified Drinking Injury) is typically found the morning after a heavy drinking session.

More Detail...

The injured party usually has no recollection whatsoever about how the injury occurred. The "Hangover" series of films offers lots of good examples of UDIs (the most obvious example being when dentist "Stu Price" wakes up to find a tooth missing). All the films are based on determining how UDIs occurred.

An Academic Look at UDI

UDI is an initialism abbreviation. This means it is pronounced using its individual letters (i.e., Yu Dee Aye). Initialisms contrast with acronyms, which are spoken like words. UDI is typically used as a noun. Of note, the abbreviation UDI attracts the article "a" as opposed to "an" because it starts with a consonant sound (Yu). However, when spoken or written in full, it attracts "an" because it starts with a vowel sound (uh).
