inadvertent cock-block 

when your roommate cock-blocks you inadvertently, just because he/she lives there and wants to go to sleep, making it not really his/her fault, but frustrating all the same. This becomes even more frustrating when your partner has roommates as well, leaving you completely dry.

Last night I got hit by an inadvertent cock-block. Talk about frustrating.

Jill: I'm pretty sure that violates both FERPA and HIPAA at the same time. What an inadvertent professional error.

Anne: God I hope we're insured.

When the whipped eggs go into the pan then you suddenly realize you have all the good veggies 🌶 hiding in the fridge to quickly wash chop and cook before the eggs cook all the way through. Clock's ticking!

Started cooking scrambled eggs in the pan then suddenly realized I had all the complimentary veggies hiding in the fridge to make an inadvertent omelet happen before the point of no return.
