The acronym and abbreviation for the now gone but, not forgotten "Southern Pacific Railroad" . As it was something of a household name throughout the West Coast and other Western States due to its involvement in creating the modern day California, Oregon, Nevada, Utah, Texas, Arizona, New Mexico, etc...... .Entire towns and cities were built and created for and by the SP. Los Angeles would never have become so overgrown had the owners of the SP not facilitated it by owning and developing the real estate.

1. "Service Provider", used in "escort review" forums to refer to a working girl, painted lady, lady of the night...
2> "Standard Play", the shortest runtime on media formats which offer a choice between SP (standard play), LP (long play), EP (extended play). For instance , the VHS video home system had T120 as the standard videocassette, which held two hours (120 minutes) of SDTV on SP, four hours on LP, six hours on EP. The lowest denominator (supported from the first VHS VCR onward) was SP, which forced some particularly long feature films (like Mario Puzo's "Godfather" series) onto a second cassette.
3. "Service Pack" in software version numbering; "WinXP SP3" was Windows XP, Service Pack 3, for example.

I miss the VHS days. It wasn't HDTV, but when you booked an SP you actually had two hours to "get off".

Abbreviation for super piled. If you're drinking alcohol, particularly ipas, once you're intoxicated you're piled. Once you've had even more you are super piled or SP. The next day when you're hung over you are also considered SP. Also if you are substantially overweight you are considered piled. Your appearance and body shape is piled. Like a pile of shit. Possibly super piled if morbidly obese. SP
