Poker lines borrow the game's whole psychology: bluffing, reading tells, knowing when to go all in. That structure is what makes them land — the listener knows the metaphor's stakes. Card rooms, casino bars and home games are the venue; mid-hand is not, and most tables will tell you so.
The all-in and bluff material works on non-players too. The pot-odds jokes are strictly for people who know what pot odds are.
Poker lines are really about attention — reading tells, calling bluffs, betting big — which is why they translate beyond the felt. On apps they signal wit; at a home game they are table banter; at a casino they work best at the bar, after the session, when chips are no longer at stake. Mid-hand delivery marks you as a tourist in both games.
The wider gambling floor has its own material in the casino collection, and the risk-taking register carries into fight night lines for the adrenaline crowd.
