Amusement park buddy

Somebody you go to the amusement park with.

Guy 1-You gonna take your amusement park buddy to the amusement park?
Guy 2- My amusement park buddy has already been on all the rides there 10 times. Amtrak doesn't offer the number of rides she's already been on, it's not just a rumor, its true. I'm not the only amusement park buddy of hers.
Guy 2-Boo, you're not the only one who's got to get rid of her.
Guy 1-She's got one less amusement park buddy, even if she's got all the amusement park buddys she needs already.
