big-headed
Swollen with ego
Big-headed means having an exaggerated sense of one's own importance or abilities.
Someone who becomes big-headed after success has let it inflate their ego: He got a little big-headed after his promotion.
The literal sense—having a physically large head—exists but rarely appears outside medical contexts.
