When romantic feelings/infatuation has reached a point where various human functions that would usually be deemed gross and/or repulsive such as; farting, boogers, body odour, bad breath, menstruation, just to name a few become the norm in the unforeseen blink of loves eye.
Tom is spending the night at Shelly's, they are cuddling in her bed when suddenly Tom casually yet forcefully pushes out a monster fart which should repulse Shelly but instead she embraces him and kisses his cheek. Totally infartuated.
(n.)That audible, nasty, rumbling sound created from holding in flatulence, most of the time uncontrollable except by avoiding gassy food in the first place. Although infarts do not smell, it's very embarassing in public since it can be quite similar to a real fart.
(v.)To sound an infart
A: Did you just infarted?
B: Yeah, guess I held it in for to long.
A: And why does it smell anyway?
B: Oh well...uh, bye.
an infart: a fart that once is held in for an extended time, becomes farted internally (instead of externally) and still relieves the stress of gas buildup. highly suggested in pubilc social situations.
