date a fatty with a cute face, then be like
"damn you're so beautiful"
 
she'll be like 
"how? im a fat monster, im not beautiful!"
 
you get up right in her chipmunk face and say
"you are gorgeous! both inside and outside dammit!"
"i fell in love with a diamond that society has brainwashed into believing she isn't!"
now turn slighty to the side and in a low tone, whisper "damn you society! . . . .  damn you to hell!"
 
(cue the rocky training theme)
she is inspired by your sudden need to work out and encouraging her to be your gym partner
she starts a diet and working out, before you know it
your overweight investment is starting to deliver dividends 
she will forever see you as the only man that stood by during her land monster phase
 
she will suck yo dikk, no problem!
