Commuterbation 

Masturbating discretely while on public transportation. Often done via pockets in trousers. More daringly, while sitting down, some individuals will even unzip their fly and insert hand into area with the concealment of a bag on lap.

I was on the subway last night and this smoking hot chick sat in front of me. I put my hands in pocket and immediately commenced vigorous commuterbation.

commuterection 

The uncontrollable erections caused by the swaying of the subway, often ending in embarassing stares from fellow commuters.

I was leaning against the door, and it gave me a massive commuterection

commuterection 

An unintentional, likely undesired erection caused by the wide range of vibrations encountered while riding public transportation.

Due to the questionable state of the train tracks between stations Chabanel and Parc, Jeremy received a raging commuterection and was forced to hold an umbrella in front of his crotch.

commputercation

A mark of success in communicating thoughts and ideas through a computer device. The purpose and goal of commputercating.

I get e-mails from guys all the time on OK Stupid, but there is very little in the way of commputercation going on, just a bunch of requests for photos. Ugh!
