How do you make a Facebook application forget you ever used it?

[XxGxX]

I'm using the "I Would Rather Be" application and I've made a trip that I really want to delete. Because it won't let you delete trips, is there any way to make it forget you so you can start completely over?
With some applications even if you remove it and then get it back again, all your old information is still there. This is one of them.

Try removing the application and then adding it again.. enter everything again

just uninstall/removed the account/program first then stall all over again.

Delete it (aka remove it) and it should be gone. Then you can add it again. If that doesn't work, you can block it.
