1.
massively (adj.)

A word that is the equivalent of the phrase "requires very much ponder" or, "requires an extreme degree of thought"---possibly of British origin---used as an adjective. In particular, it is used at the end of a sentence as somewhat of an afterthought preceded and followed by an ellipsis (...) said in a room with people present. This is not the letter ending and indicates that the speaker is trying to describe something too huge to express in mere words.
