NEW YORK, July 21 (Xinhua) -- Donald Trump on Thursday officially accepted nomination as the Republican presidential candidate, but the historic moment for the New York billionaire was somewhat overshadowed by his "air kiss" to his running mate.

Many described the scene as awkward, noting that Trump's attempts to show affection for Indiana governor Mike Pence was met with obvious resistance.

"Forehead access denied. LOL," appeared repeatedly among comments of the GOP Convention drama, and here are some of the witty responses by Twitter users:

Ronan Farrow:

When you move a little too fast on the first date.

My biggest fear is that Donald Trump tries to kiss me ... Mike Pence, I will pray you get through this.

It's dope that conservative are down with the male-on-male air kiss. Trump always zigging when they zag.
