MtT 

Transphobic term used by the gender critical/TERF community. Basically saying that they are Male to Transgender (MtT) rather than Male to Female (MtF).

Person 1: "Did you hear that our friend turned out to be MtF transgender? She looks amazing now."

TERF: "Umm did you mean MtT? I don't believe that transgender people exist."

MTT is the theory of the fact that it takes a certain amount of time for a meme to travel through the ages of children. MTT is usually increasing the lower the age is. The elementary schoolers have such a high MTT that you would see them whipping and doing the nae nae in 2018.

MTT 

Acronym for "Man Tank Top". Identical to the wife-beater which should only be worn by females. The kind of "man" that wears this is typically cocky and think they have a jesus-like physique.

Also can be used as nickname for said type of males.

"LOL did you see Grant wearing a MTT on friday?!"

"MTT strikes again!"

mtt 

Means: Hmong Thailand in the Hmong language. Used by dumb American hmong people who cannot spell in the hmong language. It should really be spelled HTT for Hmong Thailand. It refers to Hmong people who were born in Thailand and moved to the US. Similar to FOB.

He's so lame and mtt.

MtT 

Male-to-Trans. A feminist revision of the more commonly known "MtF" (male-to-female). Meant to clarify that even if a trans-identified adult human male person changes appearance through hormones or surgery to align with a personal feeling of gender, the sex of the individual can never actually be changed to female (the physical change is only "skin deep").

I quit using the Orwellian term "MtF"; MtT is more accurate and neutral.
