short for "Down To Make Blanket Forts". Like "DTF" (Down To Fuck) minus the sex.

Also a slick way for a guy to get a girl into a bed without saying "DTF' or "lts get in a bed".
Girl: I really miss childhood sometimes. Dont you just wanna be young again sometimes?
Guy: hmmm... DTMBF?
Girl: This is why I love you.
