== It is also a verb that means "to be cheated" == 

 The word "fuck" in "I got fucked by a scam artist" still means sexual intercourse, but in a metaphor.  To literally get fucked by a scam artist is for the scam artist to have had sex with you.  Its not true that fuck as a verb means cheated,  but to figuratively be cheated is to be penetrated sexually (screwed, raped, fucked). 

 It may be redundant to outline all the ways "to have sexual intercourse" can be used as a verb in a figurative form and then mention them as separate terms under fuck.
