Speedshitting

While dating a girl - particularly in the first awkward weeks - speedshitting refers to the act of taking a very fast shit in her appartment's/dowm room's bathroom, as to induce her to thing you were only - harmlessly - urinating.

Girl: "We spend a lot of time together...but I noticed...err"
Boy: "Yes?"
Girl "You...never seem to do a numer two!!"
Boy "Well...I was speedshitting"
