The 3 month rule refers to the time period after which a girl can be judged on her looks for real. The problem is that girls often look much fitter when they are first seen, but after 3 months, if they are still regarded as fit, then the must be a fit girl.
"hey, have you seen the new girl? She's so fit man!"
"yeah she is, but remember the 3 month rule. Only time will tell!"

Get the The 3 month rule mug.
the three month rule is the amount of time a guy gets to ask a girl out. you have three months to figure out whether or not you see it going somewhere and if you fully want to be with her. it really should take three months but if it does and you still don’t know then leave her the hell alone. stop torturing that girl. if you don’t know by the third month if you see yourself with her then fucking leave. stopping wasting her time
girl: dyk what the 3 month rule is because it’s been 3 months already, and we still a aren’t dating. like do you want me or are you wasting my time? i’ve waited long enough so now i need to know, are we gonna date or not???
boy: idk yet, i still don’t know what i want
girl: cool *blocks him*
