“
Subic bay ... Olongapo city ... sh$t river ... clap city ... San Miguel beer ... fond memories.”
I was TDY to Clark AFB twice in the early 1970’s. Loved San Miguel beer, however you never wanted to hold your beer up to a light......there were ‘things’ floating around in the bottle that I couldn’t identify. The joke was that you had to drink your beer quickly before whatever was in the bottle drank it first.

In other words until I see another source it's BS...
