A phone up one's ass

[timelets]

From an Atlantic article about California prison gangs:

“How can you tell what type of cellphone an inmate uses,” he asked, “based on what’s in his cell?” He let me think for about two seconds before cheerily giving me the answer: you examine the bar of soap on the prisoner’s sink. The safest place for an inmate to store anything is in his rectum, and to keep the orifice supple and sized for the (contraband) phone, inmates have been known to whittle their bars of soap and tuck them away as a placeholder while their phones are in use. So a short and stubby bar means a durable old dumbphone; broad and flat means a BlackBerry or an iPhone. Pity the poor guy whose bar of soap is the size and shape of a Samsung Galaxy Note.

I didn't get a chance to read Skarbek's The Social Order of the Underworld, but reviews are excellent. Even after reading just the Atlantic article about the book I feel that I understand the world governed by "понятия" much better than before.
