What is Booth Capturing?

What is Booth Capturing?: "Basic booth capturing works in the following way: At a polling center, members of a certain political party will “capture” a booth, by filling it with a stream of party loyalists. Typically these loyalists are not legally registered to vote at that particular booth, and may vote several times for their party member. By keeping the booth occupied, votes for an opposing party are kept lower, and people who have the legitimate right to vote may not be able to wait for an extended time to cast their vote, or they may be so intimidated by fierce seeming mobs capturing a booth that they simply don’t vote."
