To kick the living hell out of someones chest with the flat of the bottom of your foot.
"that midget wouldnt shut the fuck up so i sparta kicked it."
Comes from the old transformers cartoons where Starscream of the Decepticon's would always try his hardest but would somehow go wrong and Megatron the leader of the Decepticons would just say "You fail me again Starscream."
Definition: Someone who tries extremely hard but in the end it blows up in there face and everyone laughs and ridicules them.
