The Ketchup kiss is when a women on her period applys her menstral "juices" on another womens lips creating a lip- stick like substance.
Judy was nervous before the big party because she forgot her lip-stick but thankfully Carol could help. Being on her period Carol dipped her finger in her own "ink" and carefully applied it to Judy's puffy lips.
