When a person blocks another person from enjoying the greatest amount of fun. This applies to anything which blocks another person from having fun.

(Joe, the douchebag shows up)
Chris: Dammit, i'm getting fun-blocked for sure.

v. when you order/make tacos, but end up not being able to enjoy them due to a friend eating what you ordered, wrong ordering, or over-intoxication. comparable to the let down felt when one has been "cock-blocked"
person a: where's my taco, dude?
person b: "crap, i think i just ate it!"
person a: "dude, you fucking just taco-blocked me!"
person 1: "Dude we got you taco bell on our way here"
person 2: "Did you remember to order it with no fiesta?"
person 1: "Oh crap, I forgot"
person 2: "Dude, you totally taco-blocked me!"
person a: "ooh! order me a 5$ box!"
person b: "okay dude"
person a: (passes out, too drunk to eat)
person b: "you passed out, i ate your tacos"
person a: "dammit! I just got completely taco blocked!"
person b: "crap, i think i just ate it!"
person a: "dude, you fucking just taco-blocked me!"
person 1: "Dude we got you taco bell on our way here"

Intentionally making yourself visible on someone's Facebook page to discourage others from liking or commenting.
Guys are like vultures liking and commenting every time Kelli posts something so I posted a sweet meme to like block them.

A tactic used by unconfident males to coral, corner, or block off access to females they are engaging in conversation with. L-Blocking is usually preformed by propping one of their legs up on a seat near the female target.
Look at that babe getting leg blocked by that dweeb at that picnic table. See how he blocking access to her by strategically placing his leg on the seat in front of her.

Breeze Blocking sexual act. This involes doing a shit into a condom and freezing it. Once frozen this tool should be used as a dildo and inserted up either a ladies vagina or anus, or indeed a man's anus, as a way to gain sexual pleasure.
