Oklahoma was a word Ted used in couple's therapy with his wife. If invoked by one party, it obligated the other to tell the "God's honest truth".

Darsteiner
 was a brand of lager that sponsored Jamie. During a press conference to launch the relationship, he behaved appallingly. At one point he invoked the image of what he called a "brewnicorn" by placing a bottle on his forehead to emulate a unicorn. At another point, he spoke of having a "brewby", in which he tried to treat a bottle of like a baby. 
Keeley tried to send him helpful cues about how to promote the beer during the conference, but she gave up as he moved to his more ridiculous techniques. At this point, Rebecca, who was also watching the car crash of an event, offered Keeley a job in helping with branding other Richmond players. 
Scone
Ted once introduced his son to a' by saying, "It tastes like a muffin, but it sucks all the spit out of your mouth." It greatly resembled what Americans would call a "biscuit".
