v. To doggedly block someone's progress. Originally derived from the nickname a Confederate general "Stonewall" Jackson obtained at the battle of Bull Run (1st or second, i don't recall). The troops said his men were holding back the Union army like a stone wall. Hence Stonewall Jackson. So to stonewall means to delay and generally block someone.

v. When you're 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.

Bro 1: "Have you tried texting her agian? I mean it's been 4 days."
Bro 2: "If I do, then she'll know I'm into her."
Bro 1: "True. Just wait it out, don't fall for the tactic."
