What do these words mean?

Padel Citizen uses a few terms that are obvious if you already play padel — and not at all obvious if you don’t. Here’s the plain-English version.

Padel: A racket sport — like tennis on a smaller court with walls. Played in doubles. Easy to learn, fast and social.
Crew: A group of people who play together — your club, your crew, your office league. Each crew has its own roster, leagues, and events.
Organiser (a.k.a. "jefe" / "mayor"): The person who runs games and admins the group — schedules sessions, manages the roster, runs leagues. You'll see "Organiser" everywhere in the app; the underlying word is the Spanish "jefe" (boss).
Admin: A crew helper with most jefe permissions but not the founder.
Member: You. A regular player in the crew.
Americano: A 2-3 hour social session where everyone plays with and against everyone — partners change every round. Best for mixed-skill groups.
Mexicano: Like an Americano, but every round players are reseeded by points so winners face winners. Finds the strongest of the day.
KOTC (King of the Court): Winner stays on court, loser goes to the back of the queue. Whoever holds the longest streak wins the session.
Round-robin league: A multi-week season where every team plays every other team. Best record at the end takes it.
SMASH league: A premium league format: 16 players, 6 weekly matches with rotating partners (no repeats), then a Friday finals night for the top 8. Points scoring: 2-0 win = 3, 2-1 win = 2, loss = 0.
Tournament: One-day knockout — sign up as a pair, win to advance, last team standing wins. Pool format = round-robin pools that feed the bracket.
Ringer: A pre-vetted substitute. If a regular SMASH player can't make a week, a ringer subs in so the match still happens.
Career rating: Your skill rating across the app — between 0 and 100. Goes up when you win, down when you lose. Anchors matchmaking and standings tiebreakers.
Buy-in / prize pot: Some leagues (like SMASH) have a crew-voted entry fee. The pot pays out to the champion, runner-up, and a "production" budget for the after-party.
