“Shoring” is a portmanteau of ‘scoring’ and ‘whores’. A person ‘shores’ when they have sex with a girl who may be a prostitute, but no payment is involved. Bar fining is not considered shoring. Shoring only occurs when the girl is genuinely attracted to a mate. She will often forego potential earnings with paying customers in this circumstance. It is not unusual for a man to have no idea the girl is a working girl. Shoring is common practice in parts of the developing world where the majority of girls you meet at night seek resources for sex. If you shore, protection is recommended.
The word shoring was invented myself and a friend while travelling in South East Asia in the summer of 2009.
