look up any word, like cunt:
synonym for drunk texts. Texts sent while "on the lash"; texts you usually regret, and are most of the time incoherent and vulgar in nature.
1. "dude, i'm going on the fucking lash tonight, I'll lash text you later"

2. "Man was I drunk as shit last night, I lash texted all those hoes in my phone trying to get some"

3. "Stop lash texting me you idiot and sober up. You're acting like you're on your Gap Yah"
