When you are at work and you are taking a shit and another co-worker walks in the restroom and notices the locked stall door and walks right back out.
"I was taking a shit and Aaron took one step in the restroom and walked right back out."
"Yeah dude, thats called a shit block"
"Yeah dude, thats called a shit block"

when you take the nastiest shit when your boy and his girl are making out in the other room... this shit literally interrupts sexy time.
Tom is making out with Sharlene so i guess its time to make anal explosion (shit block) to disrupt sexy time.

When you go into a public bathroom to take a dump and the stalls are occupied prohibiting you from doing your business.

Taking an awful shit in the bathroom so that nobody is able to have sex in it later. Where there is only two places left in the house to have sex and your boy has you covered on one!
James' ex and some other hot girl where going to go have sex in the bathroom but he thought ahead and shit blocked them earlier.
