Vulgar, of bad taste, loud, flashy, stupid and ugly. Bogans and female chavs often display outrageous tackiness without an ounce of shame. A vestimentary choice that says "I'm an ignorant, tasteless idiot and I'm pretty proud of it, thank you very much". A way to show your economic and intellectual poverty by dressing up in a way that immediately grabs attention, but also stabs you in both the retinas. A tacky person not only obviously lacks taste (and doesn't give a fù*$) but also really, really stands out in a crowd, and not in a good way. Someone who is very bad at basic fashion and has a totally delusional innate sense of self worth.
"David was so embarrassed when his tacky, drunken girlfriend started insulting the barman because he picked up and gave her back the panties she voluntarily dropped while obviously hitting on him that he is now is a monastery in the south of Italy, care to leave a message?"

A popular playground manouevre in Liverpool. Tackying is the act of rubbing one's hand on arse-crack, grundle and ball-bag before rubbing it in somebody's face. the Tacky is a punisnment reserved for only the worst of playground Knob-shines

In bad taste. This usage, as opposed to the physical description, originated in the rural South but has since been adopted for use nationwide and in urban settings.
Wearing a translucent blouse and a black bra is downright tacky.
