Every era has its slang
Lunfardo 2.0 Dictionary
Twenty pairs. Each 1930 word with its present-day equivalent and, where it exists, the line from the tango where Gardel sang it. Eighteen already have their verse; two remain open.

Cachada
Mockery at someone else's expense, laughing and merciless.
2026 translation
The cachada happened at the table, to your face. Today it is called bardeo and happens in a group chat, but the mechanism is the same.
Every verse is cross-checked in at least two sources: the published lyrics and the record of Gardel's recording. The tango for each word plays on Spotify. Before publishing, the Foundation confirms the transcriptions.
