Roger
The word Roger is primarily a proper name of English and French usage which means "famous with the spear" from the Germanic elements hrod/"fame" and ger/"spear".
The word is also used in radio communications to indicate receipt of a message. From around 1938 it was the military phonetic for the letter "R" abbreviation for "Received", later replaced by "Romeo".
It is also a short version of the term Jolly Roger which refers to a black flag with white skull and crossbones, formerly used by (sea) pirates since as early as 1723.
It has an old (1711) vulgar slang usage as a verb where it means to have sexual intercourse with (a woman). Used of a man.
From 1650 - 1780 was slang for the word "Penis".
