The innate ability to accurately locate and urinate in a toilet while in near or complete darkness. Similar to a bat's sonar. Applicable only to men (and technically, women who can pee while standing up).
"Man I had to piss like a racehorse at 3 this morning, but I couldn't find the light switch. Luckily my peedar was working well last night."

A man’s ability in the middle of the night to know only by hearing if you’re actually peeing in the toilet, or all over the floor.
