dial-ups

Thin or non-existent lips, the opposite of the more desirable DSLs, or "dick sucking lips". This is an obvious technological reference to the advent of broadband internet, specifically Digital Subscriber Lines or DSL as it is commonly known, as opposed to the now archaic 56kbps and slower “dial-up” modems, considered obsolete and thus less desirable by most.

“I would have taken her back to the spot for some dome but I’m not down for the dial-ups.”
