This noun is used to refer to a Nonbinary's pecs/tits. Typically, when said NB has enough mass allocated to it to become noticeable or easily spotted. As well as when the NB asks you to refer to their chest as such.

DISCLAIMER: Clarify with the Nonbinary person you are about to talk to about it, before calling their chest said term. They may just refer to their chest as a chest, pecs, tits, or boobs. So, do not assume and do not IRL autofill this for their chest. Thank you!
Person: "Dang, that dude has huge thoobs!"

NB: "Thank you."
~-----------~
Person: "What would like me to call your tits?"
NB: "Well, you can call them Thoobs, if you'd like."
