BTTS stands for both teams to score. A BTTS yes bet wins if each team scores at least one goal in the match. The final score doesn't matter otherwise: 1-1, 3-2 and 4-1 all win, while 0-0, 2-0 and 0-3 all lose.
A BTTS no bet is the opposite. It wins if at least one team fails to score.
Own goals count for BTTS, because they count towards the team's score. Most bookmakers settle BTTS on 90 minutes plus stoppage time, so goals in extra time and penalty shootouts don't count. Check your bookmaker's rules if you're betting on a cup tie.
BTTS is a match market, not a player prop, so JOPP doesn't price it directly. It comes up a lot alongside player bets in bet builders, where it's correlated with the player legs. If you back a striker to score and BTTS yes, the two outcomes are linked through his team scoring. That changes what a fair builder price looks like.
