a charm used by Harry Potter; created by the Half Blooded Prince that forces an unaware victum to immediately drop there pants and start givin'er relentlessly, despite the victims suroundings, also can be used on self for a quick and easy jerk
Harry potter became quite angry with malfoy and pointing his wand shouting, "abra ka jerkium!" Immediately malfoys pants dropped, he began to jerk is "wand" quite rapidly, the whole front row of the charms class got soaked by his creamy goodness. Herminny unfortunetly got pregant in the process due to malfoys magical jism, now Harry's even more pissed.
