Abraham, who went into the game off the back of a brace against Lazio, failed to find the back of the net against Bodo/Glimt.
The England international, 24, was about to head back down the tunnel to join the rest of his teammates in the away changing room before he stopped to give the person who threw the snowball at him a piece of his mind.
But in fairness he took it rather well as he struggled to keep a smile off his face.
Former Chelsea boss Mourinho also appeared to get a rather cold reception as he almost got hit with a snowball before the game.
The Portuguese manager had some snow thrown at him as he left the team’s training ground – but they missed their target as Mourinho made it to the bus without being directly hit.

But Roma could face an investigation after an alleged assault on Bodo/Glimt manager Kjetil Knutsen.
Goalkeeper coach Nuno Santos allegedly pushed the 53-year-old Norwegian coach into a wall in a brutal post-match attack.
Roma released a statement after Bodo/Glimt confirmed they plan to file a police complaint against Santos.
A statement from Roma read: “AS Roma would like to note that, following the conclusion of the match on Thursday evening, club directors and other members of the coaching staff remained at the Aspmyra Stadion until 00:45 local time, purely for the purpose of providing UEFA and local authorities with all the details of what transpired in the areas outside the changing rooms following the full-time whistle.
“The club has total confidence that UEFA and its various bodies will ultimately establish with clarity and precision where responsibility lies for the events that occurred, events that we have already described and explained in detail to all the relevant authorities present on site.
“Finally, the club would like to emphasise that it has always conducted itself in a manner that upholds the values of fair play and sportsmanship, both on and off the pitch: the same principles that we hope will be on display throughout next week’s second leg.”
