You've Made Your Bed (So Sleep In It)

I think it's about being cheated on personally

"You've made your bed, so sleep in it, and never call me again. You've made your bed, so sleep with him, but know i'm the best you'll get."

it implies that she's with this other guy but the guy she cheated on was better than him and she's made a mistake in giving him up.

thats my theory anyway.

I love this song though These guys rock
