IdiomThe AbsurdPortuguese

Viajar na maionese

Meaning: To talk nonsense or drift off into your own dream world.

Literally: To travel in the mayonnaise

Example: “No meio da reunião, ele começou a viajar na maionese sobre abrir um bar na Lua.” — Halfway through the meeting he went away with the fairies about opening a bar on the Moon.

English equivalent: Away with the fairies

Origin: Brazilian slang for talking nonsense or drifting off into one's own thoughts. Viajar (to travel) already meant to daydream or hallucinate, and maionese is a mixture of many ingredients, so the picture is a mind wandering through a muddle. Popular explanations, such as a mayonnaise advertising campaign that promised trips, or prison slang from Rio, are unconfirmed, and no source dates the phrase.
