v. When youre texting/messaging someone and he or she suddenly stops replying mid-conversation without any warning. Generally a tactic used by girls to make themselves appear more elusive and desirous to the guys she is texting/messaging. The goal would be for the party who is building the [stonewall] to gain a better idea of how interested the [stonewalled] party is in him/her.
The idea being that the person is putting up a stone wall and impeding your progress in the conversation, and as you cannot see over the side of the wall, you have no idea why it is there. If you try to climb the wall to [figure it out], then the other party will know your level of interest.
