The answer is in this thread already:
If you watch earlier when DW arrives at the table everyone is making fun of him.
Phil Laak: "what is in that thing? chocolate?" to DW's poser bling (which is still one of the funniest things said on HSP imo)
Esfandiari: "so when did you become good with the ladies... before or after the WSOP"
Then it cuts to Ivey soon after and he is just staring DW down like he wants to walk over and smack him in the face a few times. AJ even says "a hard look from Ivey" and Gabe says basically "I aint touching this one".
