Call back request

As a noun, the practice of "beeping" in sub-Saharan Africa refers to the cell phone phenomenon during which a person dials a number but immediately cancels the call before it is answered in order to elicit a call back from the recipient. One reason for this practice is to elicit a recipient to call back when the caller has almost run out of prepaid units for his/her cell phone but still wants or needs to talk to the recipient. In Rwanda, this practice has evolved into an art for courting between men and women, where women "beep" males in order to elicit a call back, which manifests the man's interest and willingness to pay for the woman's call. At times, this practice can be an inconvenience for the recipient, and at times, people ignore the "beeps." "Beeping" is also known as "flashing" in sub Saharan Africa, and is known as "menacing" or "fishing" in Indonesia..
