The no-tell, motel. That one run-down, half lit, half renovated lodging establishment in town; where people go to do the dirty. The rooms you can usually cop for a cheap rate.
Looks like The Loose Caboose is the only place in town that's got any vacancy. :( I hope we don't get mugged.

When you have a sex train going and there are not enough people to make a full circle. The person in the rear is referred to as the loose caboose.
My swinging friends invited me over for a party. My girlfriend won't go. It is throwing off the numbers for the sex train. I hope I get to be the loose caboose rocking the train.
