Literally, every single person can relate to wanting to drop their toxic friends right around October for 2 reasons:
1) School started and you gave them a month to redeem themselves
2) They didn't redeem themselves and their time is up
Drop a friend October is not even planned either. It ALWAYS just happens naturally and it is because October is such a good month, that we can't let these toxic people ruin it.
Example:
Linda: Jaime keeps kissing my boyfriend behind my back and I'm sick of it.
Tina: Omg good thing it's drop a friend October. Literally, just forget about her.
Linda: OMG YES! I totally forgot. I think its time to move on from Jaime. And my boyfriend.
