look up any word, like donkey punch:
 
1.
When one is ill-stricken to the point where bodily functions are failing and one's sexual life is constantly excused due to uncontrollable coughs, runny noses, sneezes, etc.
*Boy and Girl lean in for a kiss*
*Boy coughs*
*Girl leans back*
Boy: Aww man. I just totally got coughblocked.

*Boy and Girl are having sex*
*Boy sneezes in Girl's face*
Girl: That was a huge turn off. I'm leaving.
Boy: Aww man. I just totally got coughblocked. Again!
