Here's an example in "Everytime" by Tatyana Ali (some people here have probably heard it)
Bridge: "I always said I'd never cry over you, but it's hard to hold back tears when your fears come true, I'm sitting here lonely just missing you, baby come home"
Chorus: "Everytime you go away, my heart goes with you, everytime you go away, my heart's torn in two, is there something I can say, won't you change the plans you made, 'cause my heart can't stand the pain, everytime everytime you go away"
So the bridge is the part that comes before the chorus.
