truphemism
A literal statement that could be interpreted as a euphemism due common usage as such.
Mrs. Jones mowed the lawn while Mr. Jones choked the chicken. The phrases "mow the lawn" and "choke the chicken" could be considered euphemisms for other activities, if in fact, Mrs. Jones was not cutting grass in the yard and Mr. Jones was not assaulting the said animal, thereby making it a truphemism.
