I use alright and okay quite a lot, though usually when someone keeps talking to me and I'm not particularly interested or really having nothing to add..
"sounds like a plan" "that figures" "fuck them up their stupid asses" "jah meen" "hell yeah", but its usually slurred together to sound something like "eeuuueeeea" "man, furreal" "holy fuckface batman" or prolly the most used one is "right behind you" (used at work CONSTANTLY)
