The erection that one finds themselves with over the course of the school day. This erection always occurs when ones mind wanders off from the lecture at hand during the last 2 minutes before the period is over. This occurs as a means to create the awkward "boner tuck" or "boner shield" created by notebooks to prevent it from being seen. The boner is not a direct result of any sexual fantasy, but as a way of your body playing the "let's see how awkward this can get" game.. Tricky bastard
"What is he doing with his notebooks?"
"Oh dude, he totally has drift-wood and is shielding"
"RYAN HAS A BONER!" (Yell to everyone in the hall)
