Referring to a pair of breast in the mind of one who is not trying to watch pornography (masterbating while imagining a pair of Breast instead of watching porn). Use this term "Blank Titties" in a emergency post nut clarity situation in which an important decision must be made within a matter of minutes while a young simpletons mind is fogged with horniness.
Damn bro, Alex's girlfriend texted me in the middle of class that she wanted to hang yesterday, I had to dip into the bathroom and bust a fatty before I texted her back, and the wifi blocks all porn bro. I had jack to some "Blank Titties". Thank god too I almost said yes.
