Marth has arrived means you are on your period
*woman walks into a room of women* Martha has ARRIVED!!
Going Martha means when you're so drunk that you have that blank look in your eyes and you go completely nuts beyond control I.e. throwing things, saying mean things, punching the walls, going ballistic.
Last night my husband was so drunk and was saying some vile things to me, he was going Martha.
person 1: omg they make such a cute couple!
Person 2: i know right? They are like xrhstos and martha.
