snack coma 

A state of sudden drowsiness following a meal or snack,

After school I had a grilled cheese Sammich and then I slipped off into a snack coma.

sack coma 

Passing out due to the sight of blood when trimming your balls with a razor.

Tried to trim my balls for my lady and wound up in a sack coma.

snackoma 

When you so many snacks and have an overload and have to sleep them off.

My girlfriend was hungry and ate too many snacks and put herself into a snackoma for so long we missed dinner.
