Crossblock 

The act of going thru a green light and blocking the intersection cuz the traffic at the next light up is not moving. Your light turns red and the traffic merging on cannot go cuz your dumbass is blocking the intersection.

OMG! That dude is totally crossblocking and I missed my green!

Cropblocked 

When your are in a picture with a hot girl, only to find out she or someone else has cropped you out of it; most of the time to make it a more appealing facebook default. Usually a limb or portion of your face still remains in the photo, letting everyone know you weren't important enough to be kept in it

I was totally cropblocked out of kelli's facebook default, fml

Crockblock 

Given the option, when your significant other prefers a family member's company to spending time with you (typically holiday or other family time).

The crock pot serves as reference to all things domestic, familial, and unsexy that occur which challenge your romance with your significant other.

NOTICE: Sexiness/utility of crockpot in actual reference may strengthen, weaken, or otherwise alter the effect of this joke, i.e. an old curbside filth-ring layered crockpot may breed disgust and contempt for your significant other's choice, while a sleek top of the line ionic self materializing crockpot may cause your P1 to either

(a) fail to sympathize with your crockblocked status OR (b) hang up the phone to go buy a comparable crockpot.

P1: " You're free tonight? I thought you flew down with Francis?!"
YOU: " I did, but Mama Dukes said Francis could the learn the family gumbo recipe, so I'm free."
P1: " Your old lady leads the parish in Crockblocking, but that IS some good gumbo."
