What not to do in Iowa.

#1 Cockblock

Cockblock – a slang phrase used to describe a situation in which one person has been prevented from flirting or establishing sexual relations with another by a third party. The term is generally used in situations where a male attempting to get close to a female has been thwarted by the efforts of another male. This second male is usually, but not necessarily known by the first and these efforts may or may not be intentional. Amongst people with relaxed gender definitions, it is possible to "cock block" a woman.
