A gateway hug is similar to a gateway drug in the sense that it leads to something more. A gateway hug leads to excessive making out, blowjobs, or consequently sex.
Took this girl out for the first time last night, got the gateway hugs. Woke up at her place the next morning.

Dude: I'll tell you, spooning is a real gateway hug. As soon as we started, I wanted to rip my pants off.
