Sophia, you are literally the only girl I know... who wouldn't have a fling with a cowboy. 見於《The Longest Ride》10：56
【fling】a short and not very serious sexual relationship (deliberately short-term sexual relationship between two people. Longer than a one-night stand, not as serious-sounding as "affair", more frankly physical than the discreet or twee "dalliance", the word has the associations of a much-needed sexual relief from stress, worry or hangups. No deep personal involvement required, just the sex and a bit of attention.)
〔affair〕
a secret sexual relationship between two people, when at least one of them is married to someone else
〔one-night stand〕
a situation in which two people have sex once and then do not have a relationship with each other
∴ affair > fling > one-night stand
