A boss or supervisor, who has absolutely no standards for his or her employees, and barely expects you to show up, let alone on time. The good part of having a lala guy (or gal) at your job, is that you can pretty much do whatever you want, including: smoke dope, study japanese, kill people and drink their blood (did I say that out loud), swap paychecks with the guy making more money than you, and pull off double shifts from the comfort of your own living room. Unfortunately, with a lala guy in charge, NOTHING ever gets done, and the work environment eventually turns into the island from Lord of the Flies.
Phoebe: Man, I miss my last boss, he was a lala guy.
Allison: Didn't he let you pull a 108 hour shift once.
Phoebe: Yup, I swiped in and went home, and didn't show up for the rest of the week. Then when I finally came back in, he gave me an employee of the week award.
