A chant that is used by a large group on a single person to convince them to do anything. The chant is as follows: "PEER PRESSURE, PEER PRESSURE, PEER PRESSURE, PEER PRESSURE..." and is repeated until the person of which the the chant is aimed caves in to the noise and number of peers.
PEER PRESSURE is pronounced: peer (mid range tone), pressure (high tone) and the "r" from the peer often runs into the "p" from the pressure.
I never want to do a beer bong again! The only reason I did it that time is because of that stupid peer pressure chant!
