Had one in MHT, I was the FO and PF winds were report by tower as we were taking the runway as 180@18ish and gusting(straight down runway 17), during the T/O roll at about 100 to 110kias, it felt like someone kicked the airplane in the right side, displacing it a couple feet left of the centerline. About 2 seconds later the CA called and excuted the abort(FO's don't do aborts at this airline). Apparently the Airspeed had stopped accelerating at 110kias for 2 to 3 seconds. As we taxied clear of the runway, the tower then reported winds of 350@20 and gusting (straight tailwind).

We were full of paxs and had to return to the gate for the highspeed abort inspection.
