What are some sneaky ways y'all get through blocks?

What are some sneaky ways y'all get through blocks? I don't know about y'all, but I can generally feel a block or a stutter coming. I enjoy engaging with people in both social and professional settings. As one can imagine, I regularly find a block or stutter coming while speaking to groups of people. The most seamless method I've found to circumvent blocks and stutters is to change my vernacular and speak more in colloquialisms. If its a professional setting I'll walk that fine line between social and professional. Real talk though I just start cursing. I'm known for having a mouth so no one notices when I start dropping f-bombs. The f-bomb is like the master key to speech impediments. What are some smooth ways y'all get through?
