Tod: 'Man, tits a bit nipply outside'
Girlfriend: 'Excuse me honey?'
Tod: 'It's cold outside dear, and your nipples sticking through your shirt only adds to the effect.'
Girlfriend: 'Hehe :)'
A massive nipple that covers the entire breast can also be mistaken for large hoover accidents. (when somebody is accidently sucked on by a hoover and has a large red circle mark left behind)
