A one legger is a term used in the world of sales. They refer to a sales appointment, meeting, or pitch, where one of two or more decision-makers are present. The present individual, of course, cannot proceed with the sale without consulting the other decision-maker (the other leg) first.
A sales appointment in which the salesperson shows up to a client's house, only to find one spouse not home. The sale is not completed as the present spouse (the one legger) must talk it over with the non-available spouse.

when you take a dump and are able to cleanly leave the toilet after only one butt wipe. Technically a "no-wiper" because the one wipe was just a confidence check. Living on the wild side would be rolling the dice and not wiping at all.
I was upset when I had to poop after I just took a shower, but I was less irritated when it turned out to be a one wiper.

This person usually will have an even story or event worse than the situation you are or have experienced. The opposite of a "one-upper"
I was telling Maria about how I wrecked my motorcyle last week and Crystal, the one-downer, proceded to explain how she was in an accident and lost her leg, punctured a lung and apparenly the hospital food was shiite and came back to life as hedgehog..
