A sexual practice in which sex toys (dildos, vibrators, butt plugs, etc.) are replaced with lizards of all shapes and sizes. The bigger the lizard, the better the orgasm. Typically, the person on top screams "KYS" upon ejaculation, thus creating a Calvin-induced super-orgasm. The cult calling themselves "The Reptilian Army" are known for praciticing this tactic everytime they have intercourse without fail.

Someone that is a complete bad ass. Or in other words, a BAMF.
