This is part of a centuries old Muslim tradition, where prospective "martyrs" are given a big "bachelor party" just before the operation. This is to get them whipped into a fever to "martyr" themselves, to give them a taste of the 72 virgins and fountains of wine awaiting them in Allah's "big whorehouse in the sky Paradaise".
They have been doing this at least since the era of the "assassins" which is derived from "hashish", from the stoned orgy parties the "martyrs" got before setting out on their missions. After these pre mission parties, with wine, hashish and girls, the "martyrs" go rushing for death, eager to cross to the "other side" and get to their eternal drunken orgy which they believe the Koran promises them.
I kid you not.
