I like your shoelaces is a catchphrase and Tumblr meme used as a covert way for users to identify fellow Tumblr users in real life or on other platforms. The expected response to the phrase is "Thanks, I stole them from the president," which serves as a reference confirming the speaker's familiarity with Tumblr culture.
The phrase became closely associated with Tumblr's early-2010s culture and was later revived through increased interest in Tumblr nostalgia. As the site's older memes and trends became subjects of nostalgic discussion, "I like your shoelaces" came to be referenced ironically as a relic of Tumblr's past.
The exchange is now generally regarded as one of the more dated and particularly cringeworthy examples of Tumblr culture, often invoked ironically to parody the site's earlier community norms.
