hit (something) out of the (ball)park
To do or perform something extraordinarily well; to produce or earn an exceptional achievement. An allusion to hitting a home run in baseball that lands outside the stadium. Great job on that report, Jacobs—you really hit it out of the park! I'm pretty sure I hit that test out of the ballpark.
park that thought
imperative Do not forget what you were saying, because I need to change the subject. Sorry, Mark, park that thought for a minute. I need to take this phone call.
park the bus
In football (soccer), to employ all (or nearly all) of a team's active players in defending its own side of the pitch. Protecting a narrow one-point lead, it looks like the home team has parked the bus for the remaining minutes of the match.
trailer (park) trash
derogatory slur A poor, uneducated, and unsophisticated person who lives in or was raised in a trailer park. Just because I come from a caravan park doesn't make me trailer trash. I'm working on my PhD at Harvard, for goodness' sake! I don't want my daughter going out with trailer park trash like him!
