Freddie the Burping Caller and the F..ting Preacher
Apparently Freddie thinks it is the sign of being filled.
I am suspecting he is Filipino. His accent and the frequent exchanging of the sound of 'f' for a 'p' is a dead give away. This is a typical English pronounciation mistake, committed by Filipinos. Couple that with the humor like asking --- how do you reconcile burping with being filled and well, what can I say?
