The phrase comes from everyday Russian slang, where the diminutive form makes the invitation sound light and joking rather than formal. As a standalone audio clip it spread through chats and short video edits as a ready made line for proposing a drink without typing an explanation. Russian speaking users recognise the wording instantly, while others use it for its cheerful delivery. It stays popular because the plan is clear in a few seconds and fits weekend, holiday, and after work contexts.
