easy lock
Easy lock is when a woman’s so used to sex she doesn’t even need a key. She’s like a door that just swings open whenever a guy walks by.
'She’s an easy lock. I walked by and she said hi.'
'He called her an easy lock because she had sex with his brother.'
'Don’t even try, she’s an easy lock. She’s got a boyfriend, a husband, and a guy from the grocery store.'
