It's when at a party or social gathering somebody takes alcohol (usually vodka) and puts it into the punch bowl covertly to get a party started.
Yo Mike's party was mad lame last night until Chris spiked the punch. Then everyone was wasted and we had the illest time

An expression that is used when someone is at a party and they add an alcoholic beverage to the punch bowl so everyone at the party gets tipsy or drunk.
