Top Definition
The resulting fixation when someone with a nice or just particularly large pair of tits enters your immediate vicinity. Similar to the target-lock of modern laser, heat or radar guided weapons. Can also result from females wearing thin fabrics (sans bra), erect nipples and notable cleavage. Males and Females alike can attain a 'lock-on' status regardless of sexual orientation.

2. The shirt Nicole was wearing made it impossible not to have a mammory-lock-on.
