Flackrifice 

When one gets flack for sacrificing one activity for another while prioritizing.

Joe hasn't been showing up to volunteer helping adolescent hockey players because his friend is sick at the psych ward and requires company. Joe's girlfriend's younger brother plays on the team and misses the coach, so he starts whining to his sister Mary. Mary isn't fond of Joes friend John because he remorselessly broke Mary's best friends heart via a text message to call off the relationship, so she gives Joe a hard time about missing a few weeks of practices, to which he replies "oh the Flackrifice."

This is when you are playing fifa and the opponent goes through on goal with no remaining defenders to prevent him from scoring. This is when you pick your closest black defender and sacrifice him to take the straight red card and bring the attacker to the ground. Thus, it is known as a blackrifice!

Blackrifice 

The lone black character in an action/horror/sci-fi movie who dies at the very beginning so that the white guys can get away. Or not even for that. He just dies pointlessly. Often made fun of in parody movies because of the sheer absurdity.

Oh, man, there's only one black guy in that group! You know what that means? Blackrifice!
