The acronym for 'Alien Baby Baby Mama', which is an inside meme from Gillovny shippers (Gillian Anderson + David Duchovny). It started after David announced Gillian on stage at the Webby Awards; " good friend, and alien baby baby mama, Gillian Anderson!". Gillovny shippers have named it by far the most wholesome meme in the fandom.
"Did you see that abbm meme? It made me smile like an idiot!"

"Yeah I saw it! #gillovnyisreal".
