An 'Explosive Deeds' is a thunderous bowel movement, usually brought on by drinking too much alcohol. The result of an Explosive Deeds usually results in the person unfortunate enough to be experiencing it completly covering EVERYTHING in poo.
"Oh my gosh!, did you see David last night?... he drank so much, I'm sure he will be having explosive Deeds today!"
