When a male is engaged in sexual acts for long periods of time without ejaculating causing his penis to swell up and resemble somewhat as a lemon. Usually happens to opiate addicts due to the fact opiates make it hard if not impossible to ejaculate while under the influence.
"Yo dog I was fucking Trina for 5 hours straight and couldn't cum, I got severe Lemon Cock now. I just wanted to splurge so I kept goin now my shaft is swollen to the max and hurts like a mug!!"
