Fraternal Twin Name Telepathy. This is a psychic connection shared between two people with a name that sounds the same, but is spelt differently(Megan/Maegan. Steven/Stephen) . When these people say the same things at the same time, almost like jynx, you yell out FTNT!

(4:30) Maegan: I want Ice Cream
(4:31) Maegan: FTNT!
(4:31) Megan: FTNT!
