Dock Blocker 

To have a large boat that takes up an entire dock at a lakeside bar or resort.

The Dock Blocker with the huge boat took the whole dock. Fuck that guy!

Dock Blocked 

When one can’t dock a bikeshare bike because all the spaces are full in the station where you want to stop. When a bikeshare biker takes the last dock in a station preventing you from docking.

I was on time for work until some asshole dock blocked me and had bike three blocks to the next station.
