Phil does have a passion. His true love is eating.
Take for example his wedding explanation stream. He spends more time talking about how great the meal he ate at Vinny's Pizza than he spends talking about Kat or the ceremony or anything else.
Phil loves to eat. He hates to cook. Therefore he really loves going out for fast food or to a sit down restaurant. Wings trolls ask him a meme Wendy's chili question. Phil will then say he doesn't like the chili and never eats at Wendy's, yet he will describe exactly what classic menu items they have, what new limited time items, what sides he likes best, what sauces they have, etc.
He said his dream was to make enough money on YouTube where he could open his own restaurant. Phil loved doing DSP Tries It, but too many people made fun of him and he also got gout. He also gave some bullshit excuses that it takes too much time to film and the food would get cold or he can't do them anymore because he can't show his house. This is obviously not true because he has done two DSP Tries It reviews in his office.
