A literal flag colored red, if you or the flag is moving towards the other so fast as to blueshift it to green.

Everything!

Say “I love you babe!”

• Long term relationship - green
• First date - red

Say “I’ll beat you!”

• Racing a kid - green
• When stoping in the middle of the woods with your date - red

Let a fart rip

• With a friend when the room is silent - green
• On your date when she rims you - red

I can go on

Lying and pretending to know something who’s actually a complete stranger to them

When the stranger is a drunk woman in distress clearly trying to get away from a predator.

Partners who want to do everything for you.

They’re very giving, and will do you so many favors, and cater to your whims. Favorite ice cream? Let me go buy it for you! Need something from the store? I’ll go get it! Need a ride? Got you covered!

Once they have you “locked down” (married, pregnant, in a long-term lease, dependant on them for transport, etc.) they can do a 180 and suddenly “you owe them”. No more favors. Only guilt. They’ll isolate you and make every negative emotion they feel be “your fault.”

They want you to become dependant on them so they can use and manipulate you.

Be so very careful with overly kind/giving people. Never let yourself be 100% dependant on someone else. Ever. No matter how nice they are to you.

Hating the democratic party of the United States. Without any other context you would assume they are a republican. But once they start critiquing marx and explaning how Trotsky’s permanent revolution is the only viable path forward you know they are good people.

Alternatively, if someone supports the dems no matter what, that is a red flag that should never be overlooked especially when they start rationalizing their perverted beliefs by name-dropping minorities out of the blue.
