LOS ANGELES — Pictured above is a perplexed Michael Arrington receiving a strawberry milkshake — with a cherry on top — courtesy of Valleywag. Why did we have a milkshake delivered to Arrington after he blew us off at the Geek Goes Chic party, had our photographer escorted from the premises, and kicked out the dreamy Pete Cashmore of Mashable? The full report from Hollywood after the jump.

It all started innocently enough. Sugar Publishing's Rebecca Gruber was nice enough to put us on the guest list for the party, which was cosponsored by PopSugar and TechCrunch. After leaving our car with the valet we sauntered into the Vanguard, a well-known dance venue on Hollywood Boulevard, without a care in the world. The comely Bonny Pierzina accompanied your correspondent as a photographer. After running into some friends near the door, we procured sodas and set out to mingle. We stopped to admire Perry Farrell mixing hip-hop hits from the Wu Tang Clan and the Beastie Boys.

I figured I'd introduce myself to Arrington and thank him for throwing the party. That was a mistake. I shook his hand, and before I could finish saying "Hi, I'm Jackson West, the new guy at Valleywag," he huffed, rolled his eyes and walked away. Laughing it off, I suggested to Bonny she roam the crowd and get some pictures of the party goers while I circled through the rest of the venue.

But it wasn't over with Arrington. He wrangled event security, tracked down Pierzina, and told the bouncers that she wasn't supposed to be there. She was then escorted off the premises, but not before being asked where I was — presumably to be disappeared from the party as well. The hero of the night was social networking entrepreneur Nick Dynice, who suggested politely to Arrington that it was rude and tasteless to turn Pierzina out.

After a flurry of text messages, I snuck out to check on Pierzina, and found some guerilla marketers from Vimby also being asked to leave. Back inside, tasteless 1938 Media videoblogger Loren Feldman traded barbs over Valleywag's traffic (and how little of it went his way). Recent Bay Area transplant Marjorie Kase, CEO of Blogger Reps, lamented the travails of her former employer MeeVee.

The rumor started going around that Cashmore had also been ejected, which turned out to be quite true. One Hollywood agent complained that the "douchebag level" was high, even for him. Once we caught wind of the planned afterparty at the Roosevelt Hotel, we tracked down Arrington one last time to thank him for the free drinks, getting blown off again once recognized.

So there we were at the Roosevelt, enjoying some fine hamburgers at 25 Degrees and dishing with Mahalo's Sean Percival when who should sit down at a booth but Arrington. The Valleywag team thought maybe we'd buy him and his entourage a round of drinks. After explaining the situation to our sympathetic server Leah, she suggested that maybe a milkshake would be more appropriate to the evident maturity level, and we agreed.

So with a signal agreed on and the camera ready, we walked by just as the milkshake was delivered. Hope you enjoyed it, Michael — we hear they're delicious, especially the strawberry.
