Of course men can get cellulite! I found this source:
Fat by any other name is still fat. Everyone, whether old or young, curvaceous or slim, has fat cells under their skin. Cellulite occurs as these fat cells swell and the surrounding fibrous tissue changes in texture, causing a pulling effect and giving the skin a dimpled look.
Hormonal changes also contribute to cellulite, which partly explains why women are more prone to it, and genes are thought to play a part. Cellulite appears largely on the thighs and bottoms, but can be found on the inner knees, hips, lower abdomen and under the arms.
