When someone weighs them self n the morning before eating so they think they weigh lighter than they are the rest of the day. Usually done to make oneself feel better about their body.
Stacy: *weighs herself* OMG! I'm losing so much weight!
Jessie: Girl, that's just your morningweight.
When you take a shower in the morning and are incapable of getting anything done, due to lack of sleep. Usually you end up just sitting under the hot water, which does nothing other then wake you up. Similar to a Pirate Bath.
