Means to adorn, beautify, or dandify (especially men)
Comes from Cf. F. adoniser, fr. Adonis (Gr)
'Whenever I find myself growing vaporish I rouse myself, wash and put on a clean shirt, brush my hair and clothes, tie my shoe-strings neatly, and, in fact, adonize, as if I were going out -- then all clean and comfortable, I sit down to write.
-The Bibliotaph by Leon H. Vincent
