Weed Block

The act of someone, usually an innocent bystander, parking right next to you when you're waiting to buy weed, making it difficult for the deal to happen smoothly.

"There was only 2 parking spots left, so I took one, assuming Tony would park in the other, but we got weed blocked and had to walk across the parking lot with a QP"

Clock Block

Some schools have a time policy for professors which allows students to leave if the instructor does not arrive after a given amount of time. Clock Blocking is when a professor arrives just before this time expires.

It was 11:14 and we were so close to having class cancelled when Dr. Jones walked in and totaly clock blocked us.

mosh block

A person in a mosh pit who decides it is best to just stand there and ruin the vibe of the moshing. Similar to a cock block but in terms of moshing.

At the show last night, this mosh block just stood in the middle of the pits.
