A variation of the typical boner, the Full Blowner is a boner which has reached terminal capacity in both girth and length, pulsating and throbbing almost uncontrollably. It is almost always at a 180 degree angle to one's stomach, unless it is naturally crooked. The Full Blowner typically occurs just before ejaculation and has a short life span.
