(verb) when someone is super gross rich, but says to people that they are like normal people but actually they always go to concerts, buy very expensive stuff and own a large swimming pool, they also buy stuff that they already have because they're bored, plus they always snapchat what they are doing (it's almost always something cool and fun) or what they are about to buy (it could be a new iPhone or furniture for their bedroom).
Person #1: Hey dude, wanna come with me to buy a new MacBook Air?!
Person #2: Sweetheart, you bought a new laptop yesterday! What's wrong with you?!
Person #1: Hey, you can just refuse, don't get angry!
Person #2: Girl, I don't understand you, you're acting like toms...
-------------------------------------------------
Person #3: Hey sis, do you like this new pair of creepers by Riri?!
Person #4: Damn, these cost like a money-bag!"
Person#3: "Why are you so surprised?! I'm just like you!"
Person #4: "Nope, the price of my shoes never exceeds 35 dollars, yours cost 350 dollars."
(" to act like toms" means that the person is super gross rich but they pretend they're like average people)
