To eat or drink something very hastily or voraciously. A noun or pronoun can be used between "slam" and "back." Don't just slam your food back like that—take a moment to actually enjoy what you're eating! I slammed back the burger so I could get back on the road straight away. It's no wonder you have such a bad hangover from the way you were slamming drinks back last night.
