Top definition
The dildo of all dildos. Basically that special dildo that makes a girl (or guy.. if you're into that shit) insta-gasm. Shaftzillas are usually rather large, they fuck shit up, and they get the job done.
"Omg, my boyfriend had me out in like 5 seconds.. almost as good as my ShaftZilla!"
