Contraction of "shamconversation". Used to describe the practice of engaging someone in conversation without aiming to create a rapport or derive any meaningful information from the exchange. Shamversations are occasionally benign but can be of great strategic importance if executed effectively; examples are given below.
"Dude, why don't I engage her friend in a shamversation, then you can have a clear path to score a homerun"
~ as used tactically by a wingman.
"My fucking ex-girlfriend showed up a the club, so I grabbed the first hot chick I could find and started a shamversation."
~ used by a recently dumped guy to avoid social humiliation.
"This weird guy kept messaging me on Facebook, so I'm having a shamversation with him, in case he kills himself or something."
~ used to keep Internet weirdoes at bay.
Contraction of "Rugby bummer" - used to describe a less evolved sub-sect of the Homo Sapiens species. Behavioural patterns are typified by highly homoerotic tendencies acted out within an organised sporting environment (most commonly Rugby in the UK). Paradoxically, this type of individual tends to attract affluent and intelligent females - possibly owing to their grotesque steroid-fuelled physique.
"I tried to chat up that chick, but her rugbum boyfriend intercepted me."
English (UK) variation on the American term "Low resolution fox". Used to denote a female who may appear to be attractive either in a low resolution picture, or when viewed from afar IRL. However, on closer inspection it is revealed that she is in fact, fugly. Girls who fall into the LRF category often have toned & attractive bodies, but sport sub-par facial features.
"I saw this really hot girl from the other side of the club, but she turned out to be an LRF!"
