Whilst playing association football/soccer; if a player is to kick a ball using his shin (usually accidentally), often the ball rolls down the shin on to the top of the foot, the player would then put power behind it to try kick the ball in a orthodox way. This can often result in the player scooping the ball high up in to the air with little power. This would be regarded as a Shin Roller.
James: Stimmy just shinned a cross and scooped it over the crossbar, it was an open goal, what an idiot!
Andrew: What a shin roller?
James: Aye, he shin-rolled it!
Andrew: Typical Stimmy.
