Use "wanker" in a sentence
"British, and the term wanker is meaningless british slang."
"This wanker is a former German cabinet minister and parliamentary secretary in Germany's defence ministry. 19% of Germans believe the Yanks were responsible for 9/11, which may explain the success of this ridiculous tome - and also the fact that conspirozoids from around the world have chosen Berlin as the site for their big conference on September 7."
"I'd rather call him/her just plain "wanker," with "eejit" a close second."
