morbing off 

Heavy masturbation, usually done 3-4 hours a day. One can even say someone who morbs off is addicted to masturbating, and even comes up with excuses as to why he must leave, when in reality he is masturbating. Derived from MorBSouL on battle.net.

What the fuck, dude? Stop morbing off and get your ass back here.

Morning Lift-Off 

A morning erection that is naturally caused as the brains enters the REM-deep sleep phase. At this stage, the body's skeletal muscle structure relaxes and causes hypervasodilation in the capillaries of the body, resulting in said erection.
After sleeping so soundly and having a great night's rest, it is no surprise to wake up with an erection.

Waking up with a HardOn is also known as a Morning Lift-Off

A pre-breakfast gathering of classy gentlemen who unsheath their morning wood or Erections for a little masterbation party. Holding hands is optional. No Homo.

Man, I woke up this morning really lonely and just thought. "I could really use a morning-wood wack off party".
