Allons-y became the Tenth Doctor's trademark phrase during David Tennant's time in the revived Doctor Who series, a French expression meaning let's go that suited his energetic, fast-talking Doctor. Fans adopted it as a shorthand for adventure and quickly shared short clips of the line on soundboards, in fan edits and across social video. It remains popular because it is instantly recognisable to Whovians and instantly understandable to everyone else, working as a cheerful launch cue for travel, gaming and reaction content long after Tennant's era ended.
