This is a feeling where you have eaten 7-10 plates of spaghetti, and you feel like you should be high but you aren't.
"I'm spaghetti high dude. holy shit."
When you are high off spaghetti, 7-10 plates
Person 1:"I haven't had any drugs, but I am high."
Person 2:"You are spaghetti high, you had 7 damn plates, man."
