Someone who is around hungover people and feels the effects of a hangover (i.e. Stomach ache, headache, tiredness, etc.) without drinking the night before.
Damn, everyone was so blacked out last night, but I didn't have a drop of alcohol and my head is killing me today, this is totally a sympathy hangover.
...on a side note, your boy hasn't dropped a deuce since that Jack fucked me up on Sunday. This fucking constipation hangover is no joke at this point...
The sore feeling you have the morning after you do something extreme as a result of pushing your body past it’s limits with the help of adrenaline
“ hey where’s Kevin I thought he was going to come hiking with us”
“ not this time he has an adrenaline hangover from that insane track meet last night- he couldn’t even roll out of bed”
