In Jailbird on Roblox, the vote-kick seems to be triggered from the player list or chat command, but the exact steps can vary by game version. A recent Jailbird wiki changelog says kicking currently requires at least 5 votes and 75% upvotes, and the vote-kick lasts 25 seconds.

What to try

  1. Open the in-game player list or leaderboard.
  2. Click the player’s name.
  3. Look for a Votekick or Kick button.
  4. Pick a reason if the game asks for one.
  5. Wait for other players to vote.

Chat command option

Some Roblox games support a command like /votekick username or /vk username, but that depends on the specific game’s setup. If Jailbird has command-based kicking enabled, that would usually appear in the game’s chat/help text or UI.

Important note

Jailbird’s own changelog suggests the system may only let you kick teammates, so it may not work against every player in the server. That means the option may be limited by team, role, or server rules.

TL;DR

Try clicking the player in the roster and looking for Votekick first; if that is missing, test /votekick username in chat, because the exact method can vary by Roblox game.
