Godblocked refers almost synonymously to the term "cockblocked." However, this form only occurs when there are natural phenomena which only God could be controlling that are blocking your cock from vaginal penetration or other womanly pleasures.
While my girlfriend Allisyn was studying abroad in Indonesia, she sent me a letter one day saying "I miss you. Being away from you makes me realize just how much I truly love you. I want you to be my first the minute I get off of that plane back home." I was excited.
A month later, I got a call from her mother. Her mom said that Allisyn, a geology major, had been studying the contours of Mt. Krakatoa when it suddenly erupted. Her body was found three days later but she was obviously dead and her vagina had turned to obsidian. I totally got godblocked.
