I like to use impactful words or phrases and then an explanation of the setting.  Like, probably, my favorite PC game.

Fallout : A Post Apocalyptic RPG

So your Interest Check could be

We Were Only Going Fishing...and then something to indicate what you're thinking in vague terms.  Phrasing it that way indicates that either something unexpected happened or something meaningful happened.  Maybe it's a woman talking about the time her boyfriend took her out fishing and became her fiancé.  Maybe it's a story about some folks being mistaken for a pair of serial killers because they were driving the same type of car.  Maybe it's an Isekai.

Even just "We Were Only Going Fishing" works if you then explain a bit about what you're looking to do.  Is it characters telling each other stories.  Is it friends killing time because work sucks.  Is it the first time some friends have come together since Covid.  Is it set in modern times in the real world.  Is it set in a fantasy world during a Great War or a 50 year long time of peace.
