Down To Make Bad Decisions. Many times, this refers to the state of mind that college girls are in after they begin to feel slightly (read: heavily) intoxicated.
Similar to DTF (down to fuck), but intercourse is not necessarily involved.
Guy 1: Dude, are you coming to the party tonight?
Guy 2: Oh yeah man, there will be so many girls who are DTMBD. It's going to be awesome.
Guy 1: That's the spirit.
MTL means Mouth-To-Lung
DTL means Direct-To-Lung
There are MTL vapers and DTL vapers. It depends on the ohms of the coil and the type of airflow and mouthpiece the ecig has.
With MTL you inhale the vapour, so it's in your mouth, then take a second inhale (also know as taking it back) so it goes to your lungs.
With DTL you just take one inhale and it goes straight to your lungs.
Down To Hold Hands. A derivative of DTF, except instead of the person being down to fuck, which usually implies that they are not looking for a long-term relationship, DTHH implies that the person is.
