1. To make something stick onto someone or something with a liquid adhesive. Go around and paste these posters on the walls. They went through the halls pasting chicken feathers on the freshmen.

2. To strike someone very hard with one's fists, especially in the face. Almost always used in the form "paste one on (someone)." I pasted one on him after his lewd remark. She pasted one on the heckler right in the guy's eye.
