To be betrayed by a woman.
Similar to the term Stacy which some incels describe as a basic white girl 'that goes for Chads', to get Macyed means to be severely betrayed by a basic white girl who made you believe she was different.
Although an unpopular term, some use the word 'Macy' as an insult towards the traitorous woman in question.
Example 1:
Person 1: I can't believe after everything I gave Alyssa, she pulled a Macy on me and fucked off.
Person 2: Wow... I genuinely thought she was different.
Example 2:
Person : get out of my house, you disgusting little Macy! How did I even bring myself to trust your Macying little ass in the first place!?
A Macy is a backstabbing brat who couldnt care more about herself and could care less about the human race. They are usually a freaking snowflake and obivously dont belong in this world. I could not hate a Macy more in my life.
"I cant believe Macy betrayed me"
'Yeah thats Macy for you'
Oh my god can you believe what Macy said to me!!!"
Nice and loyal but will try to kill you in your sleep. She will act all nice until she tries to kill you. She will be planning it for awhile first she will run you into door and throw a volleyball at your face and then it all begins!!!!
