Iregun in English

To all my Yoruba folks, pls what is the English word for iregun. As in when you talk about what you've done for someone in the past. Sometimes pronounced siregun
 
This site says -

Iregun – A stern and sleek attitude of secretly seeking reward or recompense for deeds or favors done for another person.
 
Iregun doesn't have an English word. You can use iregun together when speaking in English.. like "why are you siregun" :D
