slumming 

Young-ish, wealthy parasites feeding off the lifestyles of the urban working classes in order to appear cool or hard. These hypocrites typically hang with their new poorer friends for a while, find out the daily grind isn't exactly what they had envisioned, get bored or scared or tired of having to actually work for once, and then return to their trust funds.

For the quintessential example of slumming, listen to Pulp's album A Different Class, and their song "Common People".

Shumming 

The profound sense of shame that accompanies an ejaculation during intercourse with a partner whom the ejaculater knows he or she does not respect or wish to be involved with for a long time, despite said partner's false perception that the relationship extends beyond intercourse; to cum with shame.

She was so shallow, vain, and dumb, but so busty that I couldn't help but let myself shum into her foul mouth.

I shummed on her tits.

I spent all night shumming on her stupid ass.

I shot my shum on those pearly whites; that shumming last night drained my balls and filled my conscience with shame - gave me a set of shamesticles.

Carl went slumming yesterday at the village. When he arrived he went into their tiny smelly apartment and spit on the floor and ripped up a couple of their rags. Also made fun of the poor kids running around in their underwear.

Bob went over the projects to rough it out and see what it was like to live a day in the life of someone who lives worse than ethiopians.
