Going Canadian 

The polar opposite of Going Comando. This usually happens when its too cold to Go Comando therefor you end up wearing at least one (or more) layer(s) of undergarments to keep the nether region warm.

Me - Dude what took you so long in the bathroom? You nearly missed the entire 3rd quarter.
Him - Sorry. I'm Going Canadian and it took me forever to get through all those layers.

Going Canadian 

To go without underwear. Sometimes meaning to wear no layer of underwear beneath a pair of long underwear or stockings/nylons. Also "going commando" or "free-balling." Used in areas of the United States.

"Hey bro, I've used up all my underwear and haven't done the laundry yet. Can I borrow yours?"
"No way. You're going Canadian today."
