Trust tells

[Gypyx]

a trust tell is when a player voluntarily keeps up a pattern that he's aware of as town, and uses it to justify a townread on him just ny the sole existance of that tell

basically, a trust tell combined these 3 points :
voluntary
alignement indicative
and pointing it out

hope that helps

difference from meta is that it's also done in the purpose of getting tr'd, while meta "just happens to be"
