Acronym meaning "Down to baby-make?" Usually used in relationships of the same sex, or involving no sexual intercourse. DTBM is not the same as DTF (Down to fuck?) as there is generally no intercourse involved, but instead, artifical insemination.
Ruben texted Logan "Dtbm?" when he though their relationship should move on to the next level.
